What I’m thinking with these fuel pump problems from that vintage is that they were using fuel pumps that weren’t designed to fit something with the depth of a 75 gallon tank. Instead they installed a standard 19 gallon tank fuel pump and used an extension hose on the inlet to reach the bottom of the tank. Under that scenario the fuel pump motor, which is designed to be submerged for cooling, would soon be high and dry when half the fuel in the 75 gallon tank was used up, causing the pump to run too hot and automatically shut down until it cooled off again.
Am I missing something here?
