Nothing goes into that tiny fuel test port. The outside is sized for a
hose.

Ok, anyone know if one of the gauges from my A/C manifold gauge set can
be
adapted to the fuel pressure testing port? These gauges measure up to
150psi (low pressure gauge). I understand that adapters are normal for
gauges to be hooked up, most times. What is usually used in that tiny
fuel
port. If I can get something in there ,it will probably have metric
threads. My gauge is english threads.Any help on how I can test for high
fuel pressure?
