4.25" Red Filler Cap with Silver Aluminum 12-Hole Cell Bung

If your fuel cell was originally equipped with an aircraft-type fill cap, this kit lets you convert it to an easy-to-use screw-on cap. This is a great upgrade for molded plastic drag racing cells sold elsewhere.

This aluminum filler cap assembly is designed to bolt on to any fuel cell with a 12 x 5 11/32" bolt pattern (Fuel Safe cells do not use this size). Both the cap and the bung are CNC machined from billet aluminum. The low-profile (7/8" high x 6 1/8" OD) bung is clear anodized with a silver finish, and the cap is anodized with a red finish. The large 4 3/4" diameter cap features ten large finger-grip notches for easy handling, even with gloves on (4 4/4" is the diameter at the inside of the notches). The 3 3/4 - 18 threads unscrew quickly with little chance of cross-threading (cap has male threads; bung has female threads). An O-ring seal prevents leaks while helping to keep the cap tight. Total assembled height approximately 1 1/16". Includes mounting hardware.

Note: Does not fit any Fuel Safe fuel cells that we carry. Fuel Safe fillers normally have a smaller 12 x 4 3/4" bolt circle. Not designed for use as a remote filler.
