Billet Fuel Bowl Cap
Straight forward part that either works or it doesn’t and this one works great. My best friend owns a machine shop and has their parts anodized so I have an eye for good machining and anodizing. I bought all three caps (Fuel, Oil, Degas) and the color was spot on from one to the next (not always an easy task with anodizing). The machine work was top-notch and the fitment was great (came with new stock caps). More of a “bling” factor with these parts but man they look good on the 7.3 and function as OEM would. Great parts.

Solid
I really should have done this years ago. Well built, solid piece. Way better than plastic could ever be and a great price.

Just what I needed
I have struggled with the parts store filters and caps, as well as trying to find a cap that would fit the Motorcraft filter. This cap solved all of my problems and was well worth the money! No more leaks from warping plastic caps. No more broken caps from the plastic bending. This thing is the solution, uses Motorcraft filter and love the pressure test port. Well done!

My mistake
It probably would of worked well on the obs which I don't have I have the 1999 f250 7.3 so the threads were different and when I removed the cap I dinged it up pretty good so figured that they wouldn't take that back for a return but seems well built and nice

Quality
Great quality and came fast. Perfect fit. A lot better than the plast OEM cap

Really high quality
The CNC quality of the cap is really good. It has a good weight and a good fit. I don't see this cap cracking when removing after a few thousand miles!

I was really surprised when it showed up in the mail. Solid, heavy duty, with beautiful machine work. I regret not buying this sooner.
