billet fuel bowl cap
my very early (build 3-98) super duty has bracket that restricts cap from screwing on. Bracket mounts engine cover. The diameter of the cover is to large.

Very satisfied
Got tired of my factory plastic caps breaking every 3 fuel filter changes, this is an extremely nice up grade the machining is a work of art

high quality, fixed my leak
My plastic cap kept leaking and this solved the problem instantly. It is expensive but you get what you pay for. The machining quality are high, and it looks very nice in the engine bay.

Fuel cap
Super high quality now I can Dave some money in the end by just getting the OEM filer instead of filter and cap combo and don’t have to worry about cracking the plastic.

Fuel Bowl Cap
This is so much better than the plastic options. You can use an actual socket, and there is no way it will ever leak. Should have done this years ago.
