2023 Mini Cooper Countryman Fuel Pump Replacement Cost

Fuel pumps do not have a specific replacement interval. Replacement becomes more common as the mileage on the car increases. Repeatedly running the fuel tank low or driving with clogged fuel filters can put additional strain on the fuel pump, shortening its lifespan.

If the engine won't start, the mechanic will check for pressure at the fuel injectors when trying to start the car. If the injectors are getting enough fuel pressure, the next step is to check that the pump is delivering enough fuel. If the pressure is low or nonexistent, the next step is to check the pump's electrical circuit. If the pump isn't receiving enough voltage or has a bad connection, the circuit may need replacing. If the pump is working but is providing low pressure or too little fuel, the mechanic will check the fuel filter, as well as the electrical and mechanical condition of the fuel pump itself.

A clogged fuel filter or problems with the electrical system powering the fuel pump can result in symptoms similar to a failed fuel pump. Have the shop verify that the pump is the problem before replacing.

The first step is to disconnect the battery, in order to reduce the chance of a fire. For pumps inside the fuel tank, there will usually be an access cover that needs to be removed. With the cover off, the technician can replace the pump and pre-pump filter screen. In some cases, fuel will need to be drained before removing the access panel. When the pump is outside the tank, the mechanic will disconnect the fuel lines, remove the pump and install the new one. Once the pump is replaced, another check will be done to ensure there are no fuel leaks and that the problem is solved.
