Worked perfect for my FRx except for the new bolts. They were not long enough to catch threads. I ended up using the old bolts from the original install. I am thinking the newer FRx's might have inset holes for these bolts. My FRx is older. Other than that it was great. So far I am actually getting 72psi fuel pressure. My old black spring must have worn out a bit since it ran around 62psi.

I had bought a couple FRx kits a few years ago and had not installed one of them. I went to install it and of course I couldn't find the hardware. One email and a quick reply solved the issue. Top quality, fast shipping, and reasonable price!

RR is the best place for power stroke parts / price and quality is the best online , not to mention the install intructions and answered questions that nobody else offers
