A Handy Guide To Fuel Pumps: Buying Tips & Types

Your car’s engine is powered by fuel pushed from the tank to the engine by a fuel pump. The transmitting unit, level arm, and gasoline filter are typically included in a complete fuel pump system, which also consists of the car fuel pump.

Due to their high cost and seeming propensity to malfunction suddenly and in waves, fuel pumps have recently been a topic of intense controversy. The mechanical fuel pump is similar to all other pumps, including the first ones that sucked groundwater and those installed on engine blocks. Each mechanical pump is identical. In essence, it consists of a rod connected to a diaphragm that, when moved, creates a vacuum that draws fuel from the tank to the other side of the diaphragm, which is then forced into the carburettor or injectors. Fuel pumps had to generate very little pressure in the early days of carburettors to provide adequate fuel to the carburettor bowl.

Fuel pumps were installed in the fuel tanks of domestic vehicles as they transitioned to fuel injection. And pressures varied from 9 to 13 psi to 35 psi; split demand pumps required up to 64 psi to start the engine before stepping down to 54 psi to maintain vehicle operation, to the newest models that now have a low-pressure pump to deliver fuel to the high-pressure pump.

Fuel Pump Buying Tips

Use only high-quality TIER 1 fuel. The fuel pump is an electrical motor; therefore, keep in mind that it gets hot. Try never to run the fuel level down below a half tank. The fuel pump was installed in the gasoline tank by the makers so that it could stay cool. This guarantees that the pump will permanently be submerged. Also, remember never to fill up when the station obtains gasoline. Fuel pump filters can never remove all the mud and deposits churned up. Regardless of the miles on it, if your car has a gasoline filter that is not in the tank, you should replace it yearly. Finally, be careful to apply an anti-ethanol agent so that the gasoline does not gel if you are not burning a fuel tank almost every week for two weeks. This fuel separation most frequently causes the failure of fuel pumps and injectors.

The most accessible approach to identifying the correct fuel pump for your vehicle, if for some reason you cannot locate it by searching your vehicle’s year, make, and model is to use the Original Equipment Manufacturer (OEM) part number from the factory fuel pump assembly.

Fuel Pump Types

Mechanical Fuel Pump: Carburetor-powered automobiles, which tend to be older models, are equipped with mechanical fuel pumps. This kind of gasoline pump won’t be standard on all new vehicles.

Electric Fuel Pump: The most prevalent form of fuel pump in automobiles operating on today’s roads is an electric car fuel pump. The electronic fuel pump, which works with the fuel injectors in your car, is located just within the gasoline tank. The electric fuel pump normally pumps gas at a higher pressure than the mechanical fuel pump.

Final Thought: The most straightforward approach to discovering an appropriate car fuel pump is to look for your vehicle’s year, make, and model if, for any reason, you are unable to locate your fuel pump.
