So when you run the fuel pump, no fuel comes out of the fuel pressure
regulator outlet? That makes sense to me.
The engine has to be running so it can pull a vacuum at vacuum hose to the
fuel pressure regulator. This pulls the diaphram which then allows the
regulator to pass excess fuel through and back to the fuel tank.
Is the vacuum hose to the fuel pressure regulator ok? When engine runs
does it pull air through that hose?
