Perfect fit for 2003 F350 7.3L

Perfect fit for 2003 F350 7.3L. Worn and deformed regulator cover replaced. Only the parts needed for installation came. The fuel flow has stopped!

Pros
  • Hands-free operation
Cons
  • Security

Perfect fit, quality parts

All quality parts and everything you need to restore your regulator. BUT there are no instructions so be careful when disassembling the regular regulator.

Pros
  • Top marks for support and durability from testers
Cons
  • Clarity

Blue Spring Update Concerns

Fast delivery Old one removed to compare with the new one. I'm concerned they'll say it's a spring blue upgrade, but from what I can see it doesn't look like it.

Pros
  • Inspires Confidence
Cons
  • The list will be long.

Excellent replacement part

Good value for money, new spring was slightly longer than original but fuel pressure was acceptable. Sometimes the packaging was the wrong size, but that wasn't a problem as I already had spare parts. I really liked the case itself, it is very well made and fits perfectly. The build quality was far superior to the factory.

Pros
  • Free for training purposes
Cons
  • Difficult to say

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.

Pros
  • Price
Cons
  • Quick Start Guide

Return seal too big, missing instructions and poppet seat

*Update - in 15 minutes**Fuel pressure jumped to 108psi. Flushed the return line, apparently it was garbage. The old return oil seal decided to come out of the nut after warming up. Relax. I tried to use from this kit but it is too big in OD. I'm sending this shit back * No plate seat included. Something has let me down. No leaks so far and fuel pressure is 77psi and I expect it will drop a bit over time. No instructions. Honestly this is really necessary with this kit as it comes with a thick…

Pros
  • Easy to use
Cons
  • No
