Fuel Pressure Problems

Alright guys, I'm starting to lose my mind. Today I installed the blue spring upgrade and my EV2 fuel pressure gauge. I installed the blue spring first so I don't have a previous reading of my fuel pressure . When I start the truck the fuel pressure only goes up to 37, and kinda bounces up and down between that and 39. I would like to hope that my fuel pressure is a hell of a lot higher than that especially after the upgrade. The truck has been and is still running great. I took it for a drive and a full throttle for a split second it actually jumped up to almost 50psi. What in the world is going on here? Has anyone else had a problem like this?? Thanks in advance

Sounds like possibly some air trapped in the line going to the sending unit for your gauge if its bouncing around alot. Just my two cents but I'd keep an eye on it to see if it gets any better after a few days.

That's kind of what I was hoping for but I bled the line going to the sender and I still get the same results.

Well I couldn't take it any longer so I tore the truck back apart and pretty much reinstalled the kit again and now I'm seeing the FP where it should be, around 63psi. I never saw anything out of place and everything seemed nice and tight. No idea what could have caused this but I'm happy it's fixed now.

If its fixed now, I'd assume it was due to air in the lines. Glad you got her fixed though!
