Need help fuel pressure is to high.
I am running a A1000 pump and A1000 bypass regulator. It pegs my gauge at 80psi And will not turn down. This is how it's set up. Any help would be great. THANKS

The lines are -8. The filter is in the back of the car next to the pump. The return line is connected to the top of the tank from the regulator with AN fittings, The regulator is brand new and so is the gauge. The gauge is on the regulator, The first gauge would peg on 60 thats as high as the guage would go. The lines are aluminum and braided lines with all AN fittings.

How is the return hooked to the top of the tank?
From what U R reporting, it sounds like there's a return restriction.
I have seen the hose liner come loose and block flow. Did you flush the lines B4 installing them?
A quiky test: Take a piece of hose, plumb it in place of the return at the reg, run it to a fuel jug. Turn on the pump. PSI now where it should be? Can you adjust it?
Yes= return line problem[s].
No= bad reg.
