Well, looks like I was barking up the wrong tree. No doubt the check valves are dirty or their springs are weak, however I did the volume test....just cranking with ignition disconnected. Ford requires 1 pint in 24 seconds. I got 2,....yes a whole quart in 24 seconds (2 pints to a quart...right?). So I'd say that pretty much confirms the pump delivery is OK. I'll do the test again at higher rpms once I have things back together.

Speaking of rpms, I wonder what speed they rate the gph on these pumps. 120 gph should produce 2 gallons per minute....just a bit under 1 gallon for the 24 second test. Doesn't matter ...just curious about the pump manufacturer's test standard.

Thanks for all the replys. If anything else happens with the pump, I'll add to this post.
