Whether your vehicle's fuel delivery system comes equipped with a carburetor or a set of fuel injectors, the system probably uses a fuel pump assembly. Carburetor-equipped vehicles usually employ a mechanical fuel pump to deliver fuel from the tank to the carburetor's fuel bowls. Once the diaphragm-type pump makes the fuel transfer, the carburetor mixes the fuel with air and feeds the mixture to the engine. Fuel injection-equipped vehicles, on the other hand, use electric fuel pumps. Electric fuel pumps are designed to pressurize fuel lines, for gas to reach the engine. Despite their differences, though, both types of fuel pump assemblies are susceptible to wear and tear. Typically, it experiences damage from extreme heat and pressure in the engine bay. Fortunately, diagnosing for a defective or poor performing fuel-pump and replacing it, if necessary, is not a challenging task for the team at Mister Starter .
