I'm Awesome
So I replaced the FPR in my truck a few months ago. It solved a lot of issues I had with the truck when I bought it. Since then, the recently replaced fuel pump died as well. I never had good fuel pressure with the pump that was installed in the truck before I got it. Once I was finally able to condemn the pump, we replaced it, added the new wiring harness, fixed the ground and called it a day. It immediately put out the 56psi required, but now the FPR makes an awful sound that can be heard inside the cab. I guess its relatively common, as these regulators are also used in some of the LS series engines which seems to be where most of the issues stem from but it is happening in the 7.4's too.
I originally purchased and installed the Delphi FP10021 which is spec'd by Rock Auto, Amazon, and various other websites as being the correct regulator for the 7.4's. Since the Delco OEM and Delphi units look to be Identical, I decided to save a couple bucks and buy the Delphi unit because they probably make it for Delco anyway. Now that the truck has sufficient fuel pressure, the FPR is buzzing. According to reviews on multiple websites (rock auto doesn't do individual product reviews which is a downer) the buzzing is common on the Delphi, Delco OEM, and Delco Professional versions as well.
I would like to get the issue fixed. I know a lot of guys have replaced these FPR's and I'd like some input on whats worked and what hasn't. My plan is to buy the Delco OEM and just pay the full money for it but since it's considered one of the worst offenders, I'll get a few opinions before moving along.
