Something else you might want to do , before you change pump , is test it. Get a gallon can or more of gas. Disconnect the inlet on the pump from the tank . Put a piece of fuel line in the can and feed the inlet to the pump . This will bypass the fuel system back to the tank . What works best when doing this is a old motorcycle gas tank . If use a regular gas can , just need to be extra careful. Just make sure the can is high enough to gravity feed down to the inlet on the fuel pump.
