Typically, you may drive for 15 to 30 minutes, and then suddenly stop working and the engine gets hot. If after letting the engine cool down it functions appropriately again — only to repeat the behavior — this is a good sign the fuel pump is failing.

Doing the repair yourself is an excellent choice. Replacing your fuel pump isn’t as hard as you might imagine. In most, you must drop the fuel tank, and first drain most gas if needed. Some vehicles have an access panel in the body to get to the top of the tank to remove the assembly without dropping the tank.

Replacing the fuel pump requires removing the fuel tank, it is a little under a 2 hour job to replace it.

The average cost for a fuel pump replacement is between $220 and $1,062 depending on vehicle and age. Labor costs are estimated between $124 and $260, while parts are priced between $95 and $854. Estimates do not include taxes and fees.

Installing a fuel pump can be difficult – especially if you’ve got a full gas tank. Plus, because fuel is flammable, the task can be dangerous. If you decide to replace the fuel pump yourself, make sure to take the necessary precautions and have a fire extinguisher on hand.

The top reasons for fuel pump failure are contamination, overheating, and the gears in the the fuel pump wearing out over time. By running on a low gas tank, the fuel in the gas tank heats up a lot quicker causing the fuel pump to overheat or even worse, run dry. Avoid leaving your gas tank low whenever possible.

A faulty fuel pump will cause major performance and drivability issues with your vehicle. If your fuel to air ratio is off and the cylinders aren’t getting the fuel, then the pistons aren’t firing and your engine is struggling to move the vehicle forward. If your fuel pump is bad enough, your car simply won’t start.

If your old pump is not delivering fuel at the specified pressure, then a new one should improve your driving situation… But unless you make engune improvements that require a better, more powerful or consistent fuel pump, the pump will only provide the same fuel the injectors require.
