Review on Yjracing Fuel Relief Pressure Spring & Seal Kit for 99-03 Ford 7.3L Powerstroke Diesel: Top-notch Performance Upgrade by Timothy Johnson

Revainrating 3 out of 5

Fur. never mind Use a good quality FPR instead.

Most of the items in this kit worked properly. except for springs and a couple of the wrong size o-rings. I need to upgrade my FPR to something really high end because what I got in this kit has fluctuating fuel pressure and is a lot less than before the rebuild.
