All vehicles with engine management systems utilise an electric fuel  pump, its purpose is to deliver fuel from the fuel tank to the engine/engine management system at the required pressure and delivery rate. The   pressure and delivery rate vary according to the vehicle to which it is fitted.
Later vehicles are often fitted with a fuel pump module/assembly which includes the fuel level gauge sender unit. It is also becoming more common place to incorporate the fuel pressure regulator into the same unit.
AZCARPARTS UK offer an ever increasing range of over 240 direct fit fuel pump part numbers, plus our range of semi universal replacement pumps. All are covered by a comprehensive 12 month guarantee and come complete with fitting instructions.
Symptoms of failure
Fuel pump failure can be partial or catastrophic. Partial failure results in poor performance, low top speed, reduced power up hills and under load and is often caused by the fuel pump reaching the end of its life. Catastrophic failure results in vehicle breakdown.
Failure of the fuel level gauge unit in the assemblies will also require the complete module to be replaced. Should the pump fail in a module/assembly the repairer can make a choice between replacing the pump only and complete assembly renewal.
Maintenance
No maintenance of the fuel pump/assembly is required and there are no internally serviceable parts.
Due to the high manufacturing tolerances used to enable the pump to attain the high pressures required of the injection system, it is essential that the fuel used is clean and when any repair work is carried out that involves disassembling any part of the fuel system the utmost cleanliness should be observed.
Ensure that the vehicle manufactures recommendations are followed regarding fuel filter replacement are followed.
Typical location
Fuel pump assemblies are usually fitted inside that fuel tank and often accessed from within the passenger compartment. Under-vehicle types are, as their name suggests, fitted under the car in a location that is as close to the fuel tank as possible to benefit from.
