Fuel Pressue Issue

I recently did an efuel conversion. After the conversion, everything was fine, have the regulator set to 60psi. Whether idling or WOT, the pressure holds. This weekend, I noticed my gauge was reading 30psi, the truck still starts and runs fine. I "deadheaded" the fuel pump, it pushed 80psi, and when off, it holds the pressure nicely.

When I hooked the pump back up, after the truck runs or after I just have the key on to make pressure (up to 30 psi), the pressure immediately drops to 0. I'm not sure were to look next. Could I have a stuck OPEN injector perhaps? I guess IF I'm lucky, it's just a gauge issue, but I doubt it. Like I said, she seem to run fine.

BTW, I recently changed my oil this weekend.

Any help is greatly appreciated.

Thanks

Update: Turned our to be the Aeromotive regulator. Checked the pressure before the the regulator at the front of the head. Pressure stayed at 80 psi and held the pressure after pump was off. Guess we'll see how good their warranty is...
