In the world of the Jeep fuel pump, there are basically two kinds of pumps to be: A mechanical Jeep fuel pump or a Jeep electric fuel pump. The two do things very differently, and they tend to supply gasoline for two very different kinds of fuel systems. So let's take a closer look at your Jeep fuel pump. If you have a mechanical Jeep fuel pump, it most likely lives on the side of the engine block somewhere near the front case. A mechanical Jeep fuel pump pulls gasoline through the lines and is generally driven by an eccentric on the engine. If you have a carburetor, you probably (though not definitely) have a mechanical Jeep fuel pump. The electric Jeep fuel pump resides way back by the fuel tank, and sometimes inside the tank itself. Not surprisingly, the electric Jeep fuel pump is driven by an electric motor, so it doesn't need to be near the engine for power. Also, the electric Jeep fuel pump pushes the fuel from the tank forward, and delivers much higher pressures for fuel injected vehicles. If you have a fuel injected Jeep, you definitely have an electric Jeep fuel pump, though late carbureted or throttle-body injected Jeeps may have also had an electric Jeep fuel pump.
