Hi this is my problem I have a bosh fuel pump, fuel press is set to 40psi using the press regulator. But after the engines warms up the press drop to 20 psi. And is not the pump the pump. Any ideas what could be wrong have this happen to anyone..

 

If it's not the fuel pump, then the only other thing is the fuel pressure regulator?

LOL it was the fuel press gauge, I bought a new one for 11bucks and the fuel press is now steady at 40psi and 50psi with 10lbs of boost. Problem solved...
