Fuel Pumps & Components

Mechanical & Electric Fuel Pumps, Pump Gaskets, Switches & Relays

There are dozens of crucial parts that ensure your vehicle's operation. A fuel pump is such a device. Earlier engines required gravity only to deliver fuel to the engine's combustion chamber, while on modern vehicles, fuel pumps are indispensable for transferring gas from the fuel tank to the carburetor or fuel injection system and then to the engine. For certain reasons, fuel pumps may eventually fail, and then they need urgent replacement.

Mechanical, electric, and turbo (in jet engines) are the basic types of fuel pump. A mechanical pump is often bolted on the cylinder head or engine block and assists the carburetor in moving fuel to the engine. The lever on the camshaft pushes a rubber diaphragm (which is inside the pump), and helps fuel to get into the basin at every opening of the inlet valve. Once the diaphragm is pushed back down, fuel is pushed out from the basin into the carburetor's bowls.

The mechanical pump operates at pressures of 4-6 psi which is sufficient for the carbureted engines, yet not enough for the fuel injection systems. Operating at higher fuel pressures (around 40-60psi), fuel injected engines require an electric pump. It is usually located inside the tank to ensure liquid fuel won't explode if the pump sparks. The pump has a permanent magnet electric motor, vane roller pump, fuel damper, and a relief valve which prevents overpressure. There's also a check valve on the pump's output side to allow for the one-way fuel movement only and maintain constant fuel pressure. The entire process is controlled by the engine computer, thereby fuel delivery is more efficient and precise in comparison with the mechanical pump.

In theory, fuel pumps are made to serve as long as your vehicle does, but some of them just don't survive. There are several reasons why. Excessive wear and tear as well as insufficient amount of fuel in the tank can cause your pump to malfunction. More reasons? Well, debris, dirt, rust, and whatever else can get into the fuel tank and reach the pump and then the engine. Oops! Failure again. When it comes to the mechanical pumps, the diaphragm which may rupture over time is most often the reason. And since electric fuel pumps are powered by electricity, poor electrical connections may cause the pump not to run.

Signs of a bad fuel pump? Well, the part is in danger if the car starts intermittently jerking. Another symptom is when your vehicle is loosing power on acceleration. Also, you might hear a peculiar noise, hum for instance. Or you'll hear nothing at all if the pump is completely damaged. What's the worst thing? The vehicle simply won't start however hard you try. Then, it will have to be towed to the car service center. But if you maintain it according to the manufacturer's manual, you'll hardly have a bad experience.

A Fuel tank sending unit is a term for the mechanical assembly inside your fuel tank which measures the level of liquid in the tank, then reports its findings to the fuel gauge on your instrument cluster. All sending units contain a "float" piece which does just what it describes - floats atop the surface of the fuel. Many automakers design the float piece as an...
