Starting new thread for same old problem.....

Well I really appreciate all the help that was offered. And I thought I had checked out the ENTIRE fuel system, and in fact I did replace the entire system, EXCEPT that elbow valve at the top pf the tank.
I am looking for a screen filter or some brass , copper or stainless steel screen to make one for on the end of the line inside the tank. The tank is very clean inside, but ya never know what could get in there. Something did to cause this?
I don't think I'd want aluminum or steel screen?

I wasn't talking about "replacing" parts but actually "testing" the system like many here said to do. A simple flow test would have uncovered a problem. Then it would have just been a simple matter of going through the fuel lines until the problem was found. That is all.

Yes I know. And I am embarrassed for not checking that one part. Should have known to.
But as for checking the flow, other than an eye test, I have no meters or gauges to do any of that. Other than a multi meter.
I suppose a guy like me should not have something like this unless I have the ability to check out everything when problems arise?
But again, thanks to everyone for all the helpful suggestions.
