Fuel Pump Tests

[amalventano1 at tds.net (Allyn)]

i would recommend throwing a cis fuel pressure regulator on the outlet of 
the pump. you would have to block off the outlet of the fpr, and run the 
return line to the catch bin. this way you are actually testing the pump 
under its normal load. its likely a bad pump could pump just as well as a 
good pump when there is no discharge pressure.

There is a pump test that requires the return line to be undone and
bridging pump for 1 minute and should get some amount of fuel pumped.
I have an A1 and a A2 pump in my fuel parts and I can not remember
which one was good or bad.  Wanted to test before taking the customary
gas bath on the install:)  Instead of trying to bench test with gas
through it how about something less volatile like H2O?  Any major
problems with having residual water in pump and then installing?
