Drag Race- late model Mustang

Want to add a little “Frank Bullitt” style to your late model Mustang?  AmericanMuscle has just the accessory for you!  The slick looking aluminum Bullitt gas cap is the first modification you need before you start jumping your ‘stang on the streets of San Fran’ a la Steve McQueen.

MyRideisMe.com provides the installation guide of a Bullitt gas cap on a 1994 Dark Green Mustang GT (McQueen would dig it!).  The Mustang you see here might look subtle but it packs a punch at the dragstrip, with its horseman banging the gears to a best of 12.85 @ 106mph on 8″ slicks and stock motor and cam.  This Bullitt gas cap will let those Camaros know this is no ordinary pony.

Follow along as we take you through the installation.  It’s very straight forward and can be done by a novice with simple hand tools in about 30-45 minutes.

Step 1: Open the box and make sure everything is accounted for and in good shape (nuts, studs, lock nuts, washers, magnets, cap and ring).  AmericanMuscle is pretty good about getting you a good unit if yours happened to be damaged or missing a component (ours was missing one of the magnets).

Tools for the job

Step 2: Here’s the tools you’ll need;  T-20 Torx bit, 7mm wrench and socket/ratchet, allen set and a file/sandpaper/dremel.

Stock gas cap removed and ready for the Bullitt cap

Step 3: Remove the 2 Torx head bolts from the stock cap which attach the cap to the body and you’re ready for the Bullitt cap.

Removing the cast hooks from the cap before installing

Step 4: Using the allen wrench, remove the investment cast hooks from the bullet cap.  They’ll need to be turned around 180 degrees and reinstalled onto the car/cap.  Our hooks required very minor deburring of the castings where the pins eject the part out of the mold.
Removing the "bumpers" so they can be trimmed"Bumpers" trimmed approximately 3/16" inch

Step 5:  Remove the “bumpers” with the T-20 torx bit, trim the bumpers just above the bolt head as seen in this picture (cut or grind about 3/16 ” off the end).

Tightening the allen screw

Step 6:  Slip the unit into place, put the studs in stock holes and re-attach the cast aluminum hooks and tighten with the allen wrench.
Fastening the gas cap lanyard

Step 7:  Install stock gas tank cap plastic lanyard first, then a washer, followed by the nut, then the lock nut using a 7mm socket /ratchet.

Step 8:  Finally tighten the lower stud using a 7mm wrench.  This takes a minute or two because there’s limited access.  Just take your time here and patience will pay off shortly.
