There is no fuel cut off.Since you ran it on another tank that rules out the boats tank. Did you also swap out the fuel line?
You have a restriction in a fuel line going to the engine. This is probably what caused the fuel pump to go bad. You will need to check all the fuel lines for interior degradation. We are finding the ethanol is destroying the fuel lines from the inside out. Many lines have an inner liner, this is to meet EPA guidelines. What happens is this liner fails and restricts the fuel. The other thing is the line softens and internally collapses.
If you have black rubber lines, rub them and if your hands get black on them, change the line.
Pull any fuel connectors from the fuel lines and look inside the line for deterioration. Finally check for any kinks caused by soft lines.
If you find bad lines, which I suspect you will, replace the lines with marine grade lines.
Post back what you find.
