Fuel Pump Tests

[amalventano1 at tds.net (Allyn)]

well, thats kind of correct.
check the chart on this page:
http://www.theoldone.com/components/fuelpumps/
flow rate depends on discharge pressure. bench testing would be ~1 galon per 
minute, while the pump will only flow ~3/4 galon per minute when installed 
in a cis-e setup (5 bar / 75 psi).
