Ever since I have put it on the fuel pressure changes by itselt. I reset it and it will stay that way for a while then it moves again. I am running a stock TBI fuel pump through AN-6 lines and the fuel pressure gauge in front of the carb about 2 inches before a 90 degree turn where it goes into the fuel rail.

Any idea's? It's hard for me to figure out what my carb is doing if my fuel pressure won't stay still.

Mine does the same thing

 

I had the same set up..My fuel pump suddenly died..so i just put a 7psi inline pump chunked the regulator and said fug it =D It pulls about 7psi even through the non working in-tank pump.
