Original equipment fuel modules, which house the electric fuel pump, typically operate for seven to 10 years before failure, depending on a variety of circumstances. Premature failures can be caused by extreme hot/cold environments, contaminated fuel or excessively running a vehicle on an empty tank. Running on empty does not keep the fuel pump fully submerged and can cause the pump to overheat.

Delphi fuel assemblies are designed to deliver an immediate, uninterrupted flow of fuel to the engine’s fuel rail and injectors at the specified system pressure, resulting in more efficient operation, the company says. Additionally, where required, fuel assemblies include integrated fuel level sensing components that deliver an accurate reading of the fuel level in the tank to the fuel gauge. Fuel modules typically include a fuel vapor pressure sensor that detects any leaks in the fuel tank or associated evaporative emissions components.

In addition, with gasoline retailers now authorized to sell alcohol fuel blends containing 15 percent ethanol, Delphi says all of its fuel assemblies have undergone durability testing to ensure that they withstand up to 22 percent ethanol. In addition, the company has upgraded many older model fuel pumps/modules designs with the latest technologies so that the Delphi replacement fuel pump will perform properly in today’s environment.
