    This cap completely fixed my 7.3s fuel bowl seam leak. I even bought a new OEM motorcraft cap and oring that didn’t fix it

    This is art work , this went on so easy the old plastic cap was not going on like it should , like it was trying to cross thread . Wish I had got it sooner and looks great !

    billet fuel bowl cap

    Posted by Jeff west on Apr 4th 2026

    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.

    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.
