I need an adjustable fuel pressure regulator for my swap, looking around everyone says theres a bunch that fit my stock rail. Where does everyone see these? My truck is a 1990 F150 with a 5.0HO. Stock fuel rail from my original motor, and has the stock 3-screw FPR.

I've found 2-screw ones, no 3-screw ones. Every thread i've seen people just posted they have an 'Aeromotive', or a 'Holley', or 'BBK' but would like to have a model number..

Btw, I do have a wideband o2 being hooked up this weekend to test.

Thanks!

 

look under mustangs when you search performance parts for the 5.0l

Thank you! Looks like the 3-screw version that I need. So i'm guessing the Mustangs and the trucks used the same fuel rail? Was under the impression they didn't.. did they also switch to a 2-screw FPR later on?

Anyways, thank you!
