Quality piece. Nice seal.

Better than OEM
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

very nice
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
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.
