Building A Custom Gas Tank - Tech

With all of the pieces now made (the top of the tank is below the bottom section in this photo) assembly can begin.

The first pieces to be tacked in place are the ends. A section of stainless is also temporarily added to both the front and back section of the bottom piece to help keep the edge straight while being tacked.

The internal baffle pieces are next, which are secured to the bottom of the tank with small tabs for extra bracing.

With the internal baffles in place, it's starting to look like something!

Next the fuel pickup tube is installed.

After the sending unit reinforcement plate is spot-welded in place, the holes are drilled and tapped.

If the car is intended to use fuel injection, this is when the brace for the TPI pump is added. Ours will use a carburetor, so this piece isn't added.

The tank can now be tacked together before the final steps are taken.

The filler neck is next, and its location has been spelled out on the work order.

The vent/roll-over bung (which shuts off the fuel flow in the event of a roll-over) is added at this point.

The finish welding on all the seams can now take place. Once done, the edges and welds are deburred and ground smooth.
