Howdy,
My van has a remanned 305 and has had carb rebuilt and complete fuel system replacement in the past three years. Mechanical fuel pump had to be replaced again on a return trip from Florida to Missouri a year ago (mechanic didn’t believe it was the pump at first because of how well it was still running), and now it’s giving me the same symptoms again. Low power, cutting out under load, will stall if I don’t let it run for 5-10 minutes before takeoff. I’ve noticed both times the issues started after a quick change from cold to warm weather. Wondering if anyone has had issues with the Delphi pumps failing frequently. TIA.


Fuel leak at line connection circled.

Triaged

The rubber diaphragm in there likely doesn't play well with ethanol in the fuel. Might be the same for that fuel hose.
