Electric and mechanical fuel pumps

Delphi has released 205 new fuel modules, three new electric fuel pumps, eight new universal fuel pumps, and 54 new hanger pump assemblies as well as 19 new mechanical fuel pumps.

Delphi has released 205 new fuel modules, three new electric fuel pumps, eight new universal fuel pumps, and 54 new hanger pump assemblies to its fuel management portfolio.

The new parts cover more than 38 million vehicles built from 1965 to 2014, including Ford, Chrysler, Dodge, Chevrolet, Mercury, Volvo, Toyota, Nissan, and Hyundai applications.

Inventory is available now.

Delphi says its fuel modules, pumps, and hanger pump 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.

Delphi’s fuel modules, pumps, and hanger pump assemblies are also designed to withstand harsh alcohol fuel blends and provide dependable, long-lasting performance, quick pressure rise and quiet, efficient operation.

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.

Original equipment fuel modules, which house the electric fuel pump, typically operate for seven to ten 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 says its fuel assemblies are built with OE-tested and validated components. As a world leader in fuel pump technology and an OE manufacturer, Delphi designs and builds its fuel modules and pumps with dependable, reliable parts that you and your customers can trust.

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

Delphi fuel pump assemblies are built with OE-validated parts and include OEM-grade wiring, electrical connectors and level sensor assemblies that deliver increased performance, durability and reliability over other aftermarket fuel pumps.

Delphi has also expanded its fuel coverage by adding 19 mechanical fuel pumps.

Part numbers: MF0100, MF0103, MF0104, MF0105, MF0106, MF0108, MF0109, MF0111, MF0112, MF0113, MF0114, MF0115, MF0116, MF0117, MF0119, MF0120, MF0121, MF0124 and MF0125.

Mechanical fuel pumps, which work with older-model carbureted systems, deliver fuel flow to the engine. Sitting at the front-lower portion of the motor, the pumps are lever-operated. An internal diaphragm draws fuel from the tank through lines running the length of the vehicle and pushes the fuel into the carburetor.

Wearable components, such as the rubber diaphragm, eventually break and cause fuel leakage. The diaphragm will wear out before the fuel pump stops operating. Because the diaphragm is sealed within the assembly, the entire mechanical fuel pump must be replaced.

With many older-model cars still on the road, Delphi understands that shops need to be able to offer customers a range of quality fuel systems – no matter the age of their vehicle. By increasing our coverage of mechanical fuel pumps, Delphi ensures shops have access to pumps for carbureted applications, as well as electronic fuel assemblies for today’s vehicles.
