A fuel pump is a critical component that moves fuel from the tank to the engine, either via mechanical action or electric pressure. Modern vehicles typically use electric in-tank pumps to deliver consistent fuel pressure for fuel injection, while older or smaller engines may use mechanical pumps. Failure often causes stalling, sputtering, or failure to start.

Key Aspects of Fuel Pumps:
1.Types: Mechanical pumps (engine-mounted) and electric pumps (usually inside the fuel tank).
2.Function: Delivers pressurized fuel to the carburetor or fuel injectors.
3.Components: Often includes a filter strainer, which can clog and signal pump wear.
4.Symptoms of Failure: Engine sputtering, power loss, surging, or failure to start.
5.Safety: When replacing, work in a ventilated area, disconnect the battery, and depressurize the fuel system.
