A fuel pump is a long-lasting piece of equipment that delivers pressurised gasoline to the engine of your Mazda. However, sometimes it can fail, and you'll need to replace it. This is a moderately complicated job that's best performed by a mechanic at a dealership's service department. A mechanic will need to get to the failed pump through the top of the fuel tank via an access panel in the passenger compartment or by removing the tank from the vehicle.

How to access the fuel pump
To access the fuel pump of a 2008 Mazda 5, a mechanic will need to get to the pump through the top of the fuel tank via an access panel in the passenger compartment or by removing the tank from the vehicle. This is a moderately complicated job and is best performed at your dealership’s service department.
The fuel pump is located inside the fuel tank and has a small electric motor to ensure that pressurised gasoline flows to the engine to power the vehicle. Along the way, the fuel passes through a filter, either inside the fuel tank or externally in the fuel flow line.
Most fuel pumps will last for the life of the vehicle but occasionally they can fail. Signs of such failure are a car that won’t start or stalls once it has started. Other times, the fuel flow can slowly become starved, causing the check engine light to come on. If you hear a whirring sound coming from your fuel tank, the fuel pump may be about to fail, since fuel pumps do not normally make noise.
If you are experiencing any of these issues, it is best to take your car to a service centre that works on Mazda vehicles and have them diagnose the problem.
