Problem with fuel MOD

[95tsiawd0330]

ok so yesterday i did the fuel rewire mod.before the mod i had fuel set at 43psi with vaccum line off.Now i finished doing the mod and i start the car up and take a look at the fuel psi and noticed it was at 44psi with vac line on so i though great i must be getting good power now.Now i remove the vac line to set it at 43psi with line off and all it did was move 2psi down so i thought that was strang.Now i try to screw the fpr in to lower fuel and all it did was stay the same i had the screw all the way out and it stayed there.if i tryed to up fuel psi it will go up with no problem.So i thought my fpr or gauge was bad so i replaced them with a good working ones and it still did the same thing.now if i put the wires back to the way it is factory i can adjust the fuel psi fine.Has anyone had this problem before???i have the walbro 255 fuel pump aem fuel rail and pte 880cc.And also i used the air line to blow air in the fuel return line to make sure the line was not blocked and that was fine.

When I upgraded to the 255 rewired I had to run a -6 supply line and use my factory supply as the return. The return isn't big enough.

did you have the same problem like i have also did you use the stock fuel filter when you changed the fuel line??
