    high quality, fixed my leak

    Posted by John on Nov 18th 2025

    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.

    Excellent upgrade over the stock cap. Well packaged and quick shipping. Nice extra that it came with an upgraded blue oring!

    Fuel cap

    Super high quality now I can Dave some money in the end by just getting the OEM filer instead of filter and cap combo and don’t have to worry about cracking the plastic.

    Fuel Bowl Cap

    This is so much better than the plastic options. You can use an actual socket, and there is no way it will ever leak. Should have done this years ago.

    Perfect

    Great fit and cooler look than the stock plastic cap. I did have to open the plug at the top to bleed air out so the duel system would maintain pressure after sitting .

    Looks great but I will say the fit is tight, so kind of have to take your time with it
