Perfect Billet Fuel Bowl Cap
I Love this Fuel Bowl Cap. Being an all aluminum piece that's mating to a steel surface, you'll want to turn it backwards a half a turn or so to ensure you've got the threads matched up correctly, then tighten down nice an slow. I would also advise putting some diesel fuel on the rings before tightening down. Seals perfectly.

Great product
This was a great purchase. No more issue with plastic fuel filter caps.
Also bought the degas cap. Works great and compliments the fuel filter cap.
Hopefully one if these days riff raff will get more oil caps made so I can have all the caps be quality. -

Heavy duty cap
Beautiful machining on this piece and perfect fit. This cap is a luxury item, but it's the last one you'll ever need for your truck.
