Fuel Pumps

Fuel pumps for carbureted engines are different than fuel injected motors. The fuel systems are different and the fuel pump is an integral part of why each is different.

Fuel injected systems usually have an in-tank electric fuel pump that is submerged in the tank. The electric pump runs the entire time the engine is running. To avoid overheating the fuel pump, it is submerged to use the fuel as a coolant. Plus, the pump is pumping fuel the entire time the engine runs. Fuel goes up the line, some is used by the engine, the rest is sent back the return line to the tank. It's a recirculating system. EFI systems are also higher pressure than carbureted systems. You would not want to hook up a carburetor to an EFI systems. The pressure is too high. Stepping it down with a fuel pressure regulator is not a good idea.

Carbureted systems can use a mechanical fuel pump or an electrical fuel pump. Electric fuel pumps for carburetors are not pumping at the same pressure as an EFI pump. Mechanical fuel pumps use the camshaft eccentric to rotate (cam lobe shape) and move the fuel pump arm to move a piston in the mechanical fuel pump. The piston motion is what pumps the fuel. Mechanical fuel pumps should be bought based on your horsepower application. Big horsepower will require a higher flowing fuel pump...simple!
