Fuel System & Exhaust Upgrades For An 1,100 HP '72 Mercury Marquis

(ANNOUNCER)>> TODAY ON DETROIT MUSCLE, GIMME

FUEL, GIMME FIRE, GIMME A WAY TO RUN THAT 1,100 HORSEPOWER BIG BLOCK IN OUR MONSTER MERCURY PROJECT. TODAY WE'LL SHOW YOU HOW TO PLUMB A FUEL SYSTEM FOR A BIG POWER APPLICATION AS WELL AS BUILDING CUSTOM EXHAUST THAT'LL LET THIS MEAN MOTHER BLOW YOUR HOUSE DOWN.

(MARC)>> HEY GUYS, THANKS FOR JOINING US. NOW WE'VE GOT OUR '72 MERCURY MARQUIS BACK HERE IN THE SHOP AND WE JUST FINISHED PUTTING AN ALMOST 1,100 HORSEPOWER BIG BLOCK UNDER THE HOOD. NOW WE'RE GETTING READY TO TURN THIS THING INTO 19 FEET AND TWO TONS OF FUN, BUT FIRST THIS THING'S GONNA DRINK A LOT OF FUEL. SO WE NEED TO FIGURE OUT HOW TO GET A

FUEL SYSTEM INSTALLED.

(TOMMY)>> NOW OFTEN TIMES WHENEVER YOU THINK ABOUT THE TERM FUEL SYSTEM, CARBURETOR COMES TO MIND. NOW THIS IS THE ONE THAT CAME OFF OF

OUR 429 ORIGINALLY. WELL SOMEBODY HAD DONE AN UPGRADE. IT'S A 600 MANUAL CHOKE VACUUM SECONDARY, AND IT RAN REALLY WELL ON IT, BUT SINCE WE'RE MAKING THAT BIG OLE POWER NUMBER WE'RE GONNA NEED A BIG OLE CARBURETOR. THIS IS HOLLEY'S 1,150 ULTRA DOMINATOR CARBURETOR, AND IT HAS SEVERAL FEATURES TO IT. A FEW OF THEM, WELL IT HAS A TPS MOUNT JUST IN CASE YOU'RE RUNNING DATA ACQUISITION. IT ALSO HAS DUAL 50 PUMPS, AND WITH ITS ALL ALUMINUM CONSTRUCTION MAKES IT A LOT LIGHTER AS OPPOSED TO THE EARLIER MODELS. NOW WE'RE NOT GONNA BOTHER YOU GUYS WITH SHOWING YOU HOW TO BOLT ON A CARBURETOR CAUSE YOU'VE DONE IT OR SEEN US DO IT A WHOLE BUNCH OF TIMES, BUT THERE IS A LOT MORE TO DO ON OUR FUEL SYSTEM.

(MARC)>> NOW TO FEED THAT BIG DOMINATOR CARB WE NEED A MASSIVE FUEL SYSTEM. SO WE TURNED TO HOLLEY AND EARLS FOR A BUNCH OF COMPONENTS THAT ARE GONNA FEED. WE'VE GOT EVERYTHING FROM THE HOSE, TO THE WIRING,

HOSE ENDS, REGULATOR, GAUGE, THE FILTERS, AND OF COURSE THE PUMP. NOW THIS PUMP, IT'S 160 GALLON PER HOUR ALUMINUM DOMINATOR PUMP AND IT IT'LL SUPPORT UP TO 1,800 HORSEPOWER. SO WE DON'T HAVE TO WORRY ABOUT STARVING THAT BIG BLOCK. AND CHECK THIS OUT, THIS IS THE LATEST FROM HOLLEY, IT'S CALLED HYDRAMAT. WHAT IT DOES IS IT ACTS AS A BLADDER INSIDE YOUR

TANK, REPLACES A TRADITIONAL PICK UP TUBE. IT'S AVAILABLE IN ALL DIFFERENT TYPES OF SIZES AND SHAPES, AND YOU CAN EVEN ORDER CUSTOM ONES. IT WORKS WITH STOCK AND AFTERMARKET FUEL CELLS, PERFECT FOR DRAG RACERS, ROAD RACERS, DRIFTERS, OR ANY TIME THE FUEL'S GONNA BE SLOSHING AROUND IN THE TANK. NOW IT HAS A 15 MICRON FILTER BUILT IN, SO

THERE'S NO NEED FOR A PREFILTER, AND WITH ITS

BLADDER DESIGN, BASICALLY IF IT'S TOUCHING FUEL IT'S GONNA GET TO YOUR ENGINE. NOW BEFORE WE CAN INSTALL IT INTO OUR TANK, WHICH WE'VE ALREADY REMOVED OUT OF OUR MERCURY, WE NEED TO DO SOME THINGS TO GET THIS TANK READY. FIRST THING TO DO IS GET THIS PICK UP AND SENDING UNIT PULLED OUT SO THAT WE CAN ACCESS THE INSIDE. THEN WE'LL GRAB A JUG OF GAS TANK FLUSH AND DUMP IT ON IN. THIS IS BASICALLY A CLEANER AND DEGREASER THAT'S NONFLAMMABLE AND NONCORROSIVE. THAT SHOULD BE GOOD. NOW THAT WE'VE GOT ALL THE CLEANER IN THERE I'M GONNA SLOSH THIS AROUND A LITTLE BIT AND GET ALL THOSE FUMES OUT.

GAS SMELL IS GONE.

(TOMMY)>> LOOKS LIKE OLE MARC HAS HIMSELF A MYSTERY NOISE INSIDE THAT TANK.

(MARC)>> WONDER HOW LONG THAT'S BEEN IN THERE. ALRIGHT SO WE'VE GOT OUR TANK ALL CLEANED OUT NOW AND DRY. SO WE DON'T HAVE TO WORRY ABOUT ANY FUMES LEFT HERE WHEN WE GET READY TO DRILL OUR HOLES. THE REASON WE NEED TO DRILL INTO OUR TANK IS CAUSE IF YOU LOOK HERE AT OUR SENDING UNIT, THIS IS THE HOLE THAT WAS USED FOR OUR FEED. IT'S REALLY NOT BIG ENOUGH, ESPECIALLY WHEN

YOU COMPARE IT TO THE DASH 10 THAT OUR PUMP REQUIRES. NOW THIS IS REQUIRED FOR THE FEED AND THE RETURN,

SO WE NEED TO DRILL TWO HOLES. WE CHOSE THE TOP OF THE TANK HERE NEAR THE VENT. WE JUST NEED TO MARK THE HOLES AND DRILL THEM.

(TOMMY)>> NOW TO DO THAT WE'VE GOT A COUPLE OF TIPS FOR YOU TO HELP KEEP THE SHAVINGS OUT OF THE TANK AND TO KEEP YOU SAFE.

SO WHERE DO YOU WANT TO GO?

(MARC)>> THIS WAY.

(TOMMY)>> AN EASY WAY TO KEEP SHAVINGS OUT OF THE TANK IS TO DRILL UP FROM THE BOTTOM SO THAT GRAVITY HELPS KEEP THEM OUT. WE'RE ALSO USING A PNEUMATIC DRILL SINCE AN ELECTRIC ONE CAN GENERATE SPARKS. A LITTLE GREASE ON THE STEP DRILL BIT WILL ALSO HELP KEEP THE SHAVINGS UNDER CONTROL AS WELL

AS ELIMINATING SPARKS. NO NEED FOR HIGH SPEED. TAKE IT SLOW AND EASY. [ DRILL SPINNING ]

(MARC)>> WE'RE GONNA JUMP ON IN HERE WITH A REAMER AND KNOCK THE ROUGH EDGE DOWN ON THESE HOLES. THEN AFTER THAT A MAGNET IS A GREAT WAY TO FISH AROUND FOR ANY SHAVINGS THAT MANAGE TO MAKE IT INTO THE TANK.

JUST LOOK AT THAT! A LITTLE EARL'S ASSEMBLY LUBE ON THE ORING FOR OUR BULKHEAD FITTING WILL HELP US TIGHTEN THE FITTING WITHOUT TEARING THE SEAL.

(TOMMY)>> WE USE A TAPE MEASURE TO FIND THE LENGTH THAT OUR PICK UP HOSE NEEDS TO BE. THESE EARL'S ULTRA PRO FITTINGS DON'T JUST WORK GREAT AND LOOK NICE, THEY'RE A CINCH TO PUT TOGETHER. DON'T FORGET THE LUBE!

AS FOR THE HOSE, IT'S EARL'S ULTRA PRO, WHICH IS THEIR PREMIUM LINE OF PLUMBING. IT'S PTFE LINED AND IS EXTREMELY FLEXIBLE. PLUS IT'S GOOD TO USE ON GAS, ALCOHOL, ETHANOL, AND E-85.

(MARC)>> WITH THE HYDRAMAT ROLLED UP NICE AND TIGHT, WE CAN WORK ON GETTING IT IN THE TANK VIA THE FILLER NECK HOLE.

ONCE IT'S IN WE CAN ATTACH OUR PICK UP HOSE.

YOU CAN SEE THAT WE HAVE MAGNETS ATTACHED TO THE CORNERS TO KEEP IT IN PLACE ONCE IT'S POSITIONED ON THE BOTTOM OF THE TANK.

THIS PART CAN BE A LITTLE TRICKY. WE'LL FISH THE PICK UP LINE TO OUR BULKHEAD

FITTING, AND THEN GET IT THREADED ON. AND IN CASE YOU'RE WONDERING, THE BRAIDED STEEL ULTRA PRO LINE CAN BE IMMERSED IN GAS NO PROBLEM. WE WENT AHEAD AND REINSTALLED OUR PICK TUBE AND SENDING UNIT ASSEMBLY BUT WE DID MODIFY THE TUBE. WE'RE NOT GONNA NEED THAT ANYMORE. SO WE BLOCKED IT OFF, BUT WE ARE GONNA REUSE A SENDING UNIT. WENT AHEAD AND REINSTALLED OUR VENT AND INSTALLED NEW HOSES HERE. THESE ARE 20 FOOT LONG EACH, THAT WAY WE CAN ROUTE THEM WHEREVER WE NEED TO ONCE WE

GET IT IN THE CAR.

(TOMMY)>> WELL LET'S GO AHEAD AND DO THAT NOW, WHAT DO YOU SAY?

(MARC)>> ALRIGHT!

(ANNOUNCER)>> STILL AHEAD WE'VE GOT TO FIND A WAY TO KEEP OUR BIG, BAD FUEL PUMP OFF THE PAVEMENT. THEN WE'LL TURN A WHOLE BUNCH OF STAINLESS STEEL TUBES INTO A GNARLY THREE INCH EXHAUST SYSTEM TO LET OUR MERCURY EXHALE NICE AND EASY. PLUS A LITTLE HISTORY LESSON ABOUT WELDING.

(MARC)>> HEY GUYS, WHILE YOU WERE GONE WE WENT AHEAD AND REINSTALLED THAT TANK AND GOT THE STRAPS TIGHT. WE RAN BOTH OF THOSE FEED AND RETURN LINES ALL THE WAY TO THE FRONT OF THE CAR, BUT WE NEED TO BREAK THE FEED LINE TO INSTALL THE PUMP. NOW THERE'S A COUPLE OF TRICKS TO THIS. THE PUMP NEEDS TO BE INSTALLED LOWER THAN THE TANK, AS LOW AS POSSIBLE, AND NORMALLY YOU WOULD MOUNT A PREFILTER AND A POST FILTER, BUT BECAUSE WE'RE USING THAT HYDROMAT WE ONLY NEED THE POST FILTER. WE DO NEED TO INCLUDE IT HERE. SO WE JUST NEED TO FIGURE OUT WHERE WE'RE GONNA

MOUNT THIS THING. ALRIGHT THIS LOOKS LIKE A PRETTY GOOD PLACE

TO MOUNT THE PUMP.

THERE'S A POCKET HERE IN THE FLOOR. SO WE CAN GET IT UP, GET IT AWAY FROM WHERE ANYTHING ON THE ROAD IS GONNA HIT IT. WE CAN PROBABLY MOUNT IT THIS WAY HERE. THAT'LL KEEP IT AWAY FROM WHERE THE EXHAUST IS GONNA BE. THE MUFFLER'S PROBABLY GONNA BE RIGHT IN HERE. SO WE'LL MAKE A BRACKET.

(TOMMY)>> OKAY WE'RE NOT GONNA MAKE

THIS TOO COMPLICATED. WE'RE GONNA USE A PIECE OF EIGHTH INCH PLATE, DO A LITTLE BIT OF CUTTING, A LITTLE BIT OF WELDING, AND IT'LL BE THAT SIMPLE.

[ SAW CUTTING ]

[ SAW CUTTING ]

(TOMMY)>> ALRIGHTY, WE WENT AHEAD AND DRILLED A COUPLE OF HOLES SO THAT WE COULD MOUNT IT TO THE FRAME, AND THEN I WENT AHEAD AND CUT A COUPLE OF GUSSETS. SO NOW WE NEED TO WELD ALL THESE TOGETHER AND WE CAN MOUNT IT UP UNDER THE CAR. WE BUSTED OUT OUR ESAB MIG MASTER 280 PRO TO GET THIS BRACKET BURNED TOGETHER.

[ WELDER CRACKLING ]

(TOMMY)>> HERE YOU GO BIG GUY.

(MARC)>> THANKS, LOOKS GOOD. I WENT AHEAD AND MADE THE ENDS ON THE HOSES HERE AND WE'RE GETTING READY TO MOUNT THE PUMP. NOW IN ORDER FOR US TO DO THAT WE'RE GONNA USE THIS TOOL RIGHT HERE. NOW WHAT THIS IS LOOKS LIKE A RIVET GUN BUT IT'S THREADED NUT INSERTS. WHAT WE'RE GONNA DO IS JUST SCREW THESE ON THE TOOL HERE, SLIDE THEM IN, CRIMP THEM DOWN, THEN WE DON'T HAVE TO WORRY ABOUT THE THREADS COMING OUT.

LIKE WE SAID, WE'RE GONNA KEEP THIS NICE AND SIMPLE. A COUPLE OF 90'S WILL GET OUR LINE TO THE PUMP, AND WE'LL GET IT SCREWED DOWN TO OUR BRACKET TO KEEP IT AT HOME. WE NEED TO USE THIS FILTER IN ADDITION TO THE HYDROMAT. [ DRILL SPINNING ]

(MARC)>> THE ZIP TIES ARE TEMPORARY WHILE WE WORK

UP THE FITTINGS FOR THIS FILTER.

SOME OF THESE DEI EXHAUST BANDS WILL WORK LIKE A CHARM TO KEEP OUR FILTER IN PLACE ONCE IT'S PLUMBED.

THERE YOU GO. WE'VE JUST GOT TO WIRE IT UP WITH A 40 AMP RELAY AND WE'RE GOOD TO GO.

(TOMMY)>> NOW TO FINISH UP OUR FUEL SYSTEM WE WENT AHEAD AND MOUNTED OUR REGULATOR UP TOP. THAT WAY IT'S EASY TO KEEP A CHECK ON OUR FUEL

PRESSURE AND WHENEVER YOU GO TO DIAL IT IN YOU DON'T HAVE TO STAND ON YOUR HEAD. OH YEAH, ANOTHER THING, WE GOT OUR SOLENOIDS FOR THE

NITROUS MOUNTED UP AS WELL. NOW TO LIGHT THE FIRE ON THIS BIG BLOCK WE WENT WITH AN MSD BLASTER TWO COIL ALONG WITH ONE OF THEIR IGNITION BOXES. AND TO SEND THAT FIRE WHERE IT NEEDS TO BE WE GOT AN MSD PRO BILLET DISTRIBUTOR AND A SET OF THEIR WIRES.

(MARC)>> WITH ALL THAT TAKEN CARE OF THE NEXT THING WE NEED TO DO IS MAKE SURE THIS BIG BLOCK CAN EXHALE.

(ANNOUNCER)>> AFTER THE BREAK WE'LL SHOW YOU SOME NEW TECHNOLOGY IN THE WORLD OF WELDING THAT CAN MAKE YOUR LIFE WAY EASIER, AND IT'LL HELP US GET THAT

EXHAUST WELDED UP REAL NICE. [ WELDER CRACKLING ]

(MARC)>> ALRIGHT WE'RE GETTING TO THE POINT NOW WHERE WE CAN START INSTALLING OUR EXHAUST SYSTEM ON OUR BIG MERCURY, AND THERE'S A FEW THINGS WE NEED TO TAKE INTO CONSIDERATION. ONE OF THOSE IS THE DRIVESHAFT. NOW WE DON'T HAVE OUR DRIVESHAFT YET. WE'RE ACTUALLY GONNA REPLACE IT WITH A LARGER AFTERMARKET ONE. SO FOR NOW WE'VE JUST GOT THIS PIECE OF TUBING IN HERE. WE RIGGED IT UP, AND THAT'LL TAKE THE PLACE FOR IT. ALSO FOR THE REAR END. NOW THE EXHAUST IS GONNA LOOP OVER THE REAR END AND WHEN THE SUSPENSION TRAVELS UP AND DOWN IT COULD INTERFERE. SO WE REMOVED THE SPRINGS, THAT WAY WE CAN MODULATE THE REAR UP AND DOWN WITH THESE POLE JACKS DURING INSTALLATION.

(TOMMY)>> FOR THE EXHAUST ON OUR MERCURY WE DECIDED TO GO WITH A THREE INCH STAINLESS STEEL HOT ROD KIT FROM BORLA. WE UPGRADED OUR KIT TO THESE BIG BLOCK FORD CRATE MUFFLERS. IN ADDITION TO THOSE WE GOT A VARIETY OF MANDREL BENDS TO HELP US GET THAT EXHAUST FROM THE FRONT TO THE BACK. OF COURSE IT ALSO INCLUDES THE STRAIGHT SECTIONS YOU'LL NEED TO GET IT BACK THERE AS WELL. AND TO TOP IT ALL OFF THIS STUFF IS GONNA LOOK GREAT UNDER THAT CAR.

(MARC)>> WE'LL START BY MOUNTING THE FLANGE TO THE COLLECTOR ON OUR HEADER. THEN WE'LL GRAB A 45 DEGREE TUBE AND MARK WHERE WE WANT TO TRIM THE END DOWN TO GET IT POINTED IN THE RIGHT DIRECTION. [ GRINDER SPINNING ]

(MARC)>> WITH THAT DONE WE'LL PUT IT IN PLACE AND GRAB OUR ESAB REBEL WELDER. WE SET THIS WELDER UP WITH STAINLESS WIRE, AND WE'RE GONNA PUT IT ON THE SMART MIG MOD, WHICH WILL TAKE ANY GUESS WORK OUT OF THE SETTINGS. WE'RE DEALING WITH 16 GAUGE TUBES, SO WE'LL ROLL WITH THAT. [ WELDER CRACKLING ]

(MARC)>> ALRIGHT NOW WE'VE GOT THIS PIPE HEADING STRAIGHT TOWARD THE REAR OF THE CAR. WE'RE GONNA KICK IT IN WITH THIS 45. WE'LL CUT A SECTION OUT OF HERE AND BRING THIS PIPE OUTWARD TOWARD THE HUMP HERE. THEN WE'LL ATTACH A STRAIGHT PIPE TO IT TOWARD THE MUFFLER IN THE BACK. [ SAW CUTTING ]

(TOMMY)>> THESE ARE THE GOALS FOR THE EXHAUST SYSTEM. OBVIOUSLY WE WANT TO MAKE SURE THAT IT DOESN'T GET INTO ANY MOVING PARTS, LIKE THE DRIVESHAFT, OR GET BOUND UP IN THE SUSPENSION. WELL WE ALSO NEED TO MAKE SURE THAT IT'S TUCKED UP AS HIGH AS POSSIBLE AGAINST THE FLOOR SO THAT IT DOESN'T DRAG. [ WELDER CRACKING ]

(MARC)>> NOW TALKED A LITTLE BIT ABOUT THE PIPES WE GOT FROM BORLA, WHICH WE'RE USING TO BUILD THE EXHAUST SYSTEM HERE ON OUR MERCURY. NOW LET'S TALK ABOUT THE MUFFLERS. THIS IS A SET OF BORLA'S THREE INCH CRATE MUFFLERS, WHICH ARE SPECIALLY TUNED TO OPTIMIZE THE SOUND AND PERFORMANCE OF A BUILT BIG BLOCK FORD, WHICH IS PERFECT FOR US. NOW THEY OFFER THOSE IN THREE DIFFERENT SOUND LEVELS FROM TOURING ALL THE WAY UP TO THE SUPER LOUD ATTACK SERIES.

WE CHOSE THE "S" TYPE, WHICH IS THE MIDDLE OF THE ROAD OPTION.

[ WELDER CRACKLING ]

(MARC)>> NOW WE HAVE OUR EXHAUST ROUTED OVER THE REAR END AND FREE AND CLEAR OF ALL OUR REAR SUSPENSION. WE KEPT IT KINDA TIGHT HERE UNDER THE FRAME RAIL. THAT WAY WHEN WE PUT SOME WIDER TIRES ON THE REAR WE DON'T HAVE TO WORRY ABOUT IT INTERFERING. NOW BORLA DID SEND US THESE REALLY NICE SHINY TIPS AS WELL, BUT REALLY THE ONLY WE FOUND WE CAN MAKE THEM LOOK NICE IS TO DUMP THEM ALL THE WAY OUT THE BACK LIKE THIS. THEN WE HAVE THIS LONG TUBE HANGING OUT UNDERNEATH THE CAR. SO WE FOUND A BETTER WAY. WE'RE GONNA TAKE THESE 45'S LIKE THIS, KICK THEM OUT THE SIDE, TILT IT DOWN JUST A LITTLE BIT, DUMP IT OUT HERE RIGHT BEHIND THE REAR TIRE. LOOKS PRETTY GOOD RIGHT THERE. I THINK THAT'S WHAT WE'RE GONNA DO.

(ANNOUNCER)>> AFTER THE BREAK WE'LL SHOW YOU AN EASY WAY TO GET RID OF RUST, AND IT'S AS SAFE AS CAN BE.

(MARC)>> HEY GUYS, WHILE YOU WERE GONE WE WENT AHEAD AND PULLED OUR EXHAUST SYSTEM OUT FROM

UNDERNEATH OUR BIG MERCURY. NOW IF YOU'LL REMEMBER, WE TACK WELDED ALL THIS TOGETHER USING THAT NEW REBEL THAT WE GOT FROM ESAB WELDING AND CUTTING. WHAT'S REALLY COOL ABOUT THAT MACHINE IS NOT ONLY WILL IT MIG, BUT IT WILL ALSO STICK AND TIG WELD. LUCKY FOR US BECAUSE WE WANT TO MAKE THAT NEW EXHAUST SYSTEM LOOK REALLY NICE. THE WAY TO SET IT UP FOR TIG MODE IS FIRST TO

REVERSE THE POLARITY BY SWITCHING THE GROUND LEAD TO THE POSITIVE SIDE. THEN WE'LL GRAB THE TIG TORCH AND PLUG IT INTO THE NEGATIVE SIDE. WE'LL UNHOOK THE EIGHT PIN WIRE FROM THE MIG LEAD AND PLUG IN THE TIG ONE, WHICH ALLOWS THE MACHINE TO COMMUNICATE WITH THE TORCH.

THEN WE CAN SWITCH IT FROM SMART MIG MODE OVER TO LIFT TIG, AND THEN DIAL IN OUR AMPERAGE. 40 IS A GOOD PLACE TO START IN THIS CASE. LAST OF ALL WE'LL TURN ON PURE ARGON.

(TOMMY)>> ESAB IS THE FRONT RUNNER WHEN IT COMES TO WELDING TECHNOLOGY. ITS FOUNDER, OSCAR KILBERG, DEVELOPED THE

WORLD'S FIRST COATED WELDING ELECTRODE IN 1904. THIS REVOLUTIONIZED THE WORLDS OF CONSTRUCTION AND FABRICATION WITH THE ADVENT OF THE ARC WELDER, ALLOWING VASTLY IMPROVED STRENGTH AND SPEED OF WELDING. SO YEAH, YOU COULD SAY THAT THEY INVENTED

WELDING AS WE KNOW IT. OF COURSE OVER THE YEARS THEY'VE IMPROVED THE TECHNIQUES WITH WIRE FEEDING, GAS SHIELDING, AND TIG MACHINES, WHICH CONTINUE TO IMPROVE THE QUALITY AND CAPABILITY OF WELDERS.

(MARC)>> OUR SHOP IS OUTFITTED 100 PERCENT WITH ESAB WELDING GEAR, WHICH WE USE EXCLUSIVELY. THIS REBEL UNIT IS A GREAT MACHINE. IT RUNS ON BOTH 110 OR 220 POWER, AND WORKS GREAT FOR BOTH THE BEGINNER AND A MASTER FABRICATOR.

OH AND ONE TRICK THAT WE'RE USING TO SHIELD THE BACK SIDE OF THE TUBE IS TO PLUG ANOTHER ARGON BOTTLE INTO IT AND LET IT FILL THE EXHAUST WITH ARGON. THAT KEEPS THE INSIDE OF THE WELDS AS STRONG AND CLEAN AS THE TOP SIDE. THERE YOU GO. WE GOT OUR EXHAUST SYSTEM ALL WELDED UP. NOW ALL WE NEED TO DO IS PUT IT UNDER THE CAR.

(TOMMY)>> HEY GUYS, ONE LAST THING WE WANT TO DO

IS GET OUR BUMPERS ALL STRIPED DOWN SO THAT WE CAN SEND THEM OFF TO ADVANCE PLATING AND HAVE THEM RECHROMED.

NOW THE BACKING ON THESE THINGS ARE FULL OF RUST, AND OFTEN TIMES WE'D SAND BLAST THEM BUT FOR THOSE GUYS OUT THERE THAT DON'T HAVE ACCESS TO A SAND BLASTER WE'VE GOT SOMETHING TO GET THAT RUST OFF THAT'LL WORK JUST AS GOOD.

WHAT WE'RE GONNA USE TO GET THIS NASTY RUST OFF THIS OLD BRACKET IS EVAPORUST SUPER SAFE RUST REMOVER, AND IT SO SAFE THAT IN MOST CASES YOU CAN POUR IT DOWN THE DRAIN. NOW IT'S WATER SOLUBLE, PH NEUTRAL, WHICH MEANS

IT'S NONACIDIC AND BIODEGRADABLE, WHICH MEANS

A LOT IF YOU'VE GOT KIDS OR PETS RUNNING AROUND.

NOW WE'VE LET THIS BRACKET SIT FOR A COUPLE OF HOURS AND WHERE IT'S BEEN IN THE SOLUTION HAS TURNED ALL BLACK.

NOW ALL WE HAVE TO DO IS GET AT IT WITH THIS RAG TO SEE ALL THE GOOD THAT IT'S DONE.

NOW YOU CAN SEE THAT IT REMOVED ALL THAT OLD NASTY RUST WITH PRACTICALLY NO EFFORT.

NOW IF YOU WERE WORKING WITH A BIG PIECE, YOU COULD WRAP IT WITH A PAPER TOWEL THEN SATURATE IT WITH THE EVAPORUST, AND THEN WRAP ALL THAT WITH SOME PLASTIC WRAP, AND THEN YOU'D BE GOOD TO GO. BUT WE'RE ALL OUT OF TIME FOR NOW GUYS, WE'LL CATCH YOU ON THE FLIP SIDE.
