A pressure gauge on the suction side of the pump?? There is no pressure on the suction side to measure, there's suction or in other words a slight negative pressure.

Get a factory service manual or a Motors Manual and follow the professionally written and time tested diagnostic procedures. The output pressure of a mechanical fuel pump is determined by the diaphragm spring. The cars ran when they left the factory and then for thousands of trouble free miles.

Cars are logical animals, treat them as such
