Regardless if your car has an electric or mechanical Fuel Pump, the parts are sealed against external factors such as moisture, debris, and air that can cause performance losses or advanced wear to major engine internals. Seals and Gaskets also maintain the correct pressure in fuel pumps, absorb friction and movement due to temperature changes, and prevent fuel and air leaks. The intake manifold delivers the air/fuel mixture to the engine so it’s important to check the Intake Manifold Gasket for leaks too.
