The E-Z-GO Fuel Pump on most golf carts is a tank mount or a free-floating unit depending on who worked on it last. The thing about golf cart fuel pumps is minus a few buggies, you can use any fuel pump on any cart as long as you can get it mounted. That is not the case, unfortunately, for the 82 through 88 EZGO Marathon. These carts use an engine-mounted assembly. This means that there is a port on the crankcase that the unit mounts directly to. Because the component uses the in-out pressure created by the crankcase, using anything else is out of the question.The EZGO fuel pump on your cabbie helps the carb draw the fuel from the tank. When your golf cart is at full throttle, the carb does not even need the help of the pump, but at slower speeds, if it were not for this thing, the golf cart would not be able to run at all.
