After the car gets above 190 degrees it stumbles and will stall at a stop.

My '94 vert's fuel pressure is reading 31-37 psi. Should be 45psi right?

This should just be a fuel pump change, not the fuel pressure regulator...

Thanks as always for the advice!

It should be around 41 psi with the vacuum line disconnected. If the line is connected it will be in the 30's at idle.

With little fuel required at idle, the pressure needs to be lower than the maximum, read with the FPR vacuum line disconnected.!

It could have a leak in the fuel tank, the part between the pump & the metal like could be bad. Do a dead head test, it should hold pressure.
