This pump is only feeding numbers 2, 4 & 6. There is no fuel at the
delivery valves for 1, 3 & 5.

It runs on these three very well, I have ran it for over an hour at a time
while trying to bleed the other three. I have ran it up to 3500 RPM.

I removed and compared the delivery valves, blowing and looking through the
holder, I found no difference. I replaced the five delivery valve parts at
#1 with a known good set from my old pump, to no avail.

I exchanged transfer pumps, no good. I pressurized the fuel tank with 14
psi air, no good. I restricted the fuel return line to insure a pressure
build up, no good.

I would appreciate any ideas and/or the name and number of an expert I could
call.
