    Billett fuel bowl cap

    Thanks Clay, i have been looking for one of these for a long time in order to make a quick change fuel pressure tester. The tapped hole is perfect for the 7.3 fuel bowl fitting . It arrived today and I immediately put it to the test, perfect fit, heavy duty, well machined. As a plus now I have a spare fuel bowl cap just in case. KUDOS

    Fuel bowl cap

    Posted by Charles on Nov 13th 2018

    I was having continued problems with the plastic fuel filter and caps leaking and coming loose and I tryed basically every trick in the book trying to fix the problem short of buying a fuel bowl delete. So I figured I would take a swing at this fuel bowl cap and I was not dissapointed. Just holding this cap in your hand you can tell it was made to the highest quality and precision and I was delightfully surprised. It fit perfectly and was easy to get tight even just by hand. I've had it installed on the truck for around 1500 miles worth of driving plus quite a few hours and haven't had any leaks yet.

    I debated for days which color to get. I went with red and am super happy with it!
