This allows fuel to be pushed into the pump from the tank (caused by atmospheric pressure acting on the fuel in the tank). In doing so, the volume inside the pump chamber increased, causing pressure to decrease. Specific designs vary, but in the most common configuration, these pumps are typically bolted onto the engine block or head, and the engine's camshaft has an extra eccentric lobe that operates a lever on the pump, either directly or via a pushrod, by pulling the diaphragm to bottom dead center. A check valve is located at both the inlet and outlet ports of the pump chamber to force the fuel to flow in one direction only. Diaphragm pumps contain a pump chamber whose volume is increased or decreased by the flexing of a flexible diaphragm, similar to the action of a piston pump. Diaphragm pumps are a type of positive displacement pump.

The two most widely used fuel feed pumps are diaphragm and plunger-type mechanical pumps. If the pressure is too low, the engine may run lean, misfire, or stall.Contents1 Mechanical pump1.1 Plunger-Type Fuel Pump1.2 Decline of mechanical pumps2 Electric pump3 High-pressure Fuel Pumps4 Turbopumps5 ReferencesMechanical pump Mechanical fuel pump, fitted to cylinder headPrior to the widespread adoption of electronic fuel injection, most carbureted automobile engines used mechanical fuel pumps to transfer fuel from the fuel tank into the fuel bowls of the carburetor. If the fuel pressure is too high, the engine will run rough and rich, not combusting all of the fuel being pumped making the engine inefficient and a pollutant. Fuel pressure needs to be within certain specifications for the engine to run correctly. 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). 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 or under high pressure to the fuel injection system.
