i think some are but most guys put a B.B. from a gun under the spring. its a cheap easy fix but if i remember right, some were reporting that their pump went out a little bit after doing it. i have mine done for a year now and no ill effects. but, i dont have a pressure gauge either.

I've heard of no problems with the bb mod (as long as you use the correct size...not sure what that is but someone will chime in)...

Obviously this is not just a phenomenon that people are experiencing poor fuel pressure performance (less that 48psi during heavy throttle)...so Ford (or International) designed an upgraded spring (blue in color) that puts you in the 60-70psi range. The new kit is Ford PN# 3c3z-9t517-AG or Intl PN 1843065C95...runs about $73 bucks though. Get a fuel pressure guage so that you can monitor this important aspect of our HEUI Diesel motors.

Check out the attchment excerpt from the tech manual....It lies beneath the fuel bowls fuel pressure regulator housing cover (the four dark colored screws you see in the top pic).

the t517-AG is the fuel pressure regulator kit @ $73+ dollars...is this what you paid? The new spring should be Blue in color not Silver.

will running that high of pressure hurt longevity of any components downstream? What pressure does the fuel pump put out?

Right now I am border line ready to replace the spring because my fuel pressure is around 49psi at full load and only 50 psi at idle.

I don't want to throw in a new spring and bump pressure up to 95 psi and blow something out in the long run, I was thinking more just buy the stocker from the factory because I am not running any tunes or anything.

According to a couple of techs, you don't want to see it get lower than 48psi or over 70psi. Your's look fine...the spring should put you at 62-65psi...which is the higher, rather than lower end of the range you're in.
