In order for the engine of your BMW to run smoothly and effectively, the engine has to have the proper mixture of fuel and air. The fuel pump is responsible for providing the correct amount of fuel to the mixture.

If there is a leak in the fuel pump, then the engine will not receive enough fuel, causing it to fail to provide the power you need on demand.
