Too much fuel pressure

[69sinker]

I have an 02 5.7 pulled from a camaro along with the camaro tank in my truck and had a line bust in the tank I replaced the line and checked the fuel pressure. Gauge read 85 lbs so I pulled the pump and replaced the internal regulator. Checked the fuel pressure afterwards and it was still 85 lbs, I even checked it with another gauge and still 85. Truck runs great but why such high pressure? I am in the process of running new lines but I'm wondering what to do about this?
I have 3/8 line with inline camaro filter and return line is from rail back to tank.
