A fuel pressure GAUGE at the pressure side of the pump is a good idea.

But how come noone ever thinks to add a gauge at the SUCTION side of the pump????? One gauge reading with out the other is about as useless as no gauge at all.

THere has been alot of theoretically correct belief that vapour lock occurs on the suction side of the pump.

I doubt it. Without a gauge at BOTH suction and pressure side of pump (assuming oem pump location) then the data is nearly worthless and so is the theory of vapor lock at the suction side.
