I have 90 psi at fuel rail how do I turn it down?
I have a 90 psi at fuel rail checking it with a fuel gauge, I'm using a holley 12-600 fuel pump with a aeromotive fuel regulator, that has a return port, but I'm getting to much fuel and can't turn it down at the regulator what do you guys suggest, I'm running the ls1 camaro single line intake with no return

Is the regulator adjustable? If so and ssuming you have tried adjusting it, is it plumbed correctly? Check your return line to make sure there's no kinks in it..if everything checks out you could have a bad regulator.

Replaced the regulator and still the same tried adjusting it and it won't change, I'm thinking the pump just might be too much, the return has no kinks and it going back to the tank

That pump shouldn't be to much for your engine,, i think its a little smaller than my walbro 255..have you tried a different gauge?

What is the model number of your regulator?
