Actually, I have a manifold referenced
pressure regulator (which if I understand the concept) attempts to keep the
pressure differential between the fuel side and manifold side of the injector
constant. However, Varying engine manifold pressure (varying throttle
opening) does not appear to have any affect on my fuel pressure. It sits
rock steady at 40 psi with one pump and goes up to 43 psi with both running
regardless of throttle position.
Hi Ed,
Sounds like your regulator isn't working like it's supposed
to, though I guess it isn't causing you any problems. A simple test would
be to run the pump with the engine off and note the fuel pressure, then check it
again at idle. If you really want to get fancy, and have one of those
Mity-Vac pumps, you can just vary the pressure signal to the regulator with the
engine off. My pressure definitely
changes.
Cheers,
Rusty (wonder if Tommy got his new regulator working
yet)
