There is nothing better than sitting with your friends and comparing pictures from the trail. Make sure your gas supply problems get resolved so that you can enjoy the journey just as much as the next guy.This is not a problematic golf cart pump to replace as far as they go. You only have a few screws that mount it, but the real work comes in with the lines if you can call it that. You have one that leads up to the E-Z-GO fuel tank. This is where the gas comes in. Another line feeds the carburetor; this is referred it as output. A final line runs back to the crankcase for the pressure needed to operate this unit. An internal diaphragm drives it, which unfortunately is what causes these things to give up the ghost.This golf cart fuel pump gets misdiagnosed a lot. We will give you a few things here to look at, but calling an expert in the tech support department is your best bet in figuring out what is causing the problem. Just like ethanol is hell on the pump, it can also deteriorate the lines. Please give them a quick inspection before you order. Speaking of preliminary checks, cleaning the carb is also on this list. Over time they can get gunked up and make it seem like other things are causing the problem. Call Buggies Unlimited and get set up with the proper E-Z-GO part today.
