I got a fuel pressure regulator, a holley 4-7psi unit, and then I tuned it to midway and it worked pretty well now(this is going into two MG B carbs on my midget thow) but you can tune it to what works. /ubbthreads/images/graemlins/smile.gif

been told it should run on about 2.5 psi. Know any reason why the pump would increase in pressure like it has

This problem is kind of unusual. Are you sure the pressure gage is correct? The fuel pressure is set by the armature return spring tension. I can't imagine the spring increasing it's tension. Only other thing I can think of is that the diaphram itself has lost elasticity & is contributing to the overall spring force.
