1937 Ford Coupe dirt track racer fuel cell build and install | Redline Update #80 - Hagerty Media
There’s a lot going on in the Redline Rebuild garage—so much, in fact, that Davin needs to change locations for a bit and borrow some fabrication tools at the Hagerty Learning Center.
The 1937 Ford Coupe race car needs a metal box for its fuel cell, so Davin explains that he needs to use a shear, brake, and roll machine to build one. “Usually you buy a kit that has the bladder and the box, but since we already have a bladder … I’m going to bend up a box.”
Davin explains that it “should be pretty easy,” and he certainly makes it look that way. He builds the box in several pieces, then spot-welds it together, leaving a 1.25-inch lip on top to which he can attach the lid.
The top is a little tricky, since it requires a 6-inch hole in the center where the fuel cap sits (plus holes for the inlet and vent hoses). After taking measurements, Davin secures a board in the center of the sheetmetal, drills a hole in the board 6 inches from that center point, inserts a plasma torch into the hole, and rotates the board in a circle until the hole is cut. After smoothing the edges and punching holes along the lip, the lid is ready to be attached with bolts.
The box is a success, but after moving back to the Redline Rebuild garage, Davin doesn’t like how the cell sits inside the car. It isn’t level, and the back of the tank “is more rearward than I’d like, so I’m going to cut the braces and slide it forward 3 inches, then level it.” When that is done, Davin fabricates a brace, so the fuel cell won’t bounce around when the car is racing on the track.
Up next: leaf springs and shocks. They don’t come together as easily as Davin had hoped, so he makes plans for more cutting and fabricating. Since he’s reached the end of his day, however, that’ll have to wait until next time.
