Pat - Is it possible you got the return and feed lines swapped at the firewall when you reconnected this time.
The return line is the top metal line on mine and that rubber hose appears to be slightly smaller dia than the lower "feed" line.

I guess one way to tell is if the feed line from the fuel thermo to prefilter immediately refills itself when the key is cranked. It always drains back about 1" at shutdown.
