Speaking of regulators. I'm a bit puzzled by mine.
Until today I've been using an analog gauge, and have my fuel pressure
adjusted to 35 - 38 psi. Today I hooked up the proper sensor for the EM2. It
reads 56 PSI. The maximum adjustment on the regulator brings it down to 47 /
48. Now the analog gauge reads 30.
Can anyone explain how I tell which is right?

By the way - for Jim - the check valves on Tracy's pumps stop gravity feed,
but I think they'd handle suction from another pump and pass through fine...
but why do that? Parallel is better.

Lastly, about this air bleed thing. How does that work? Running a tank dry
(on the ground) is on my list of tests, but I haven't got to it yet.

John (wondering if 56PSI fuel pressure might explain my mixture problems)
