A fuel pump is does exactly what it sounds like it does. It pumps fuel from the fuel tank to the engine. Some vehicles to do need fuel pumps as gravity will do the work, but other do need a fuel pump.
A fuel pump is a frequently (but not always) essential component on a car or other internal combustion engined device. Many engines (older motorcycle engines in particular) do not require any fuel pump at all, requiring only gravity to feed fuel from the fuel tank through a line or hose to the engine. But in non-gravity feed designs, fuel has to be pumped from the fuel tank to the engine and delivered under low pressure to the carburetor or under high pressure to the fuel injection system. Often, carbureted engines use low pressure mechanical pumps that are mounted outside the fuel tank, whereas fuel injected engines often use electric fuel pumps that are mounted inside the fuel tank (and some fuel injected engines have two fuel pumps: one low pressure/high volume supply pump in the tank and one high pressure/low volume pump on or near the engine).
Most people think that the fuel pump can only be changed at the dealer or garage. WRONG! You can do it yourself and we have the parts to do it.
