    Great kit

    Ordered and had a tracking number in less than an hour. Fasting shipping and complete little kit. Way better than paying the shop that only wanted to replace the pump rather than fixing the leaks.

    Great O-Ring Kit!

    I wasn't really having an issue with leaking HPOP o-rings, but since I had my fuel bowl off for a rebuild, I figured that I would do them at the same time since they were easy to access while it was off. The kit was great, had everything that I needed, and the instructions and o-ring template made the project a breeze.

    I also bought the HPOP quick disconnect hose removal tool, which is a must for removing the HPOP lines and works great as well.

    Leaking HPOP

    Posted by Unknown on Aug 5th 2016

    The O'ring kit didn't have the large o'ring on the back of the pump. When I went to order it I found out about the non-serviceable plug and the threads pulling out of the aluminum body and the long thread replacement plug, which I have had to tighten several times to try to stop the leaking. If these items were included in the kit or at least the information it would be helpful.
