good info, so far i have heard only one person have a overwhelming issue. thanks for the update
What was the issue? Performance? Bad out of the box?
Base fuel pressure wont get down low enough....from too much flow at low pressures...this high flow when it meets any restriction causes a pressure rise.

So you're saying this is too much pump for a car with factory fuel lines?

you are coorect this is not a pump issue this is a return line issue. This problem is ok i wouldn't say its a good thing. It proves that the new pump is flowing more volume. Also if i remember right eric opened up the port in the regulator and its still not going down so this would prove that its a return line issue
Did the vendor (Aeromotive/Walbro) use a "turbo regal" similar fuel feed line with when recording the flow with respect to pressure numbers?
The connections where the fuel line couples near the frame rail is quite small. God help you if you damage the return o-ring and need to find the correct size and material.

Note: This is NOT the same as the injector rail o-rings.
