I live in a small town but we have a Napa. can i order one there and if so i need to know what one to order? if so what part #, spring tension or size. i have lost the end that broke off so i can compare it now.

FPS? Fuel pump spring?

CRAP!! Just read it again. what is this spring?

[Desert Rancher]

It is the IPR (injector pressure regulator) spring that is located in the fuel filter bowl assy.

A common mod is to shim the spring with a bb (from your kids red ryder). The purpose is to raise the injector fuel pressure.
Apparently Ford sold a stronger version of the spring for Cali trucks, but it is no longer available.

GDS calls it a fuel spring which is a bit confusing.

But it is interesting to note that they measured how much the stock spring degrades (looses strength) over time, which probably explains why someone with an older truck would see a difference by adding the bb shim.

Make sense?

I just need the spring that is supposed to go there.

This is the spring that you need.

GDS Fuel Spring

Otherwise go to Ford.

I heard that you are not supposed to have your fuel pressure run over 80 psi or you will ruin every seal in your fuel system.
