Our Fuel Systems Portfolio.

Fuel Injectors.

Built using OE processes and components to respond faster and last longer than the competition. Includes extra fuel filtering protection and corrosion resistance from fuel blends.

Fuel Modules and Pumps.

OE technology for immediate, uninterrupted flow of fuel to the engine’s fuel rail and injectors and more efficient operation. Integrated fuel level sensing components for accurate reading of the fuel level in the tank to the fuel guage and ECM/PCM.


Fuel Pressure Regulators. 

OE design enhances fuel control accuracy for smooth driving and emissions performance. Exclusive Nitrile™ nylon fabric diaphragms, offer protection against corrosive, high-ethanol fuels.

Other complementary products includes filters, diesel particulate filters and turbochargers.

H- Dual Filtration

Improved pump durability.

Tech Tips for Fewer Comebacks.

> Inspect the electrical connector for signs of damage such as overheated terminals and wiring. Some vehicles may be prone to failure, so it’s essential to replace the mating vehicle wiring when replacing the fuel module or pump.

> Examine the fuel tank and fuel module reservoir for contamination. If found, the fuel tank should be drained and cleaned before installing the new part.

> Also, look for rust inside the tank or reservoir of the fuel module. This indicates water is in the fuel delivery system. Metal fuel lines and fuel rails should be examined for signs of internal rust or corrosion and replaced as needed.

> Replace the fuel filter and strainer when installing a new fuel pump or module. Most fuel module kits include new strainers with the fuel module assembly. Be sure it’s correctly seated so contaminants cannot pass around it.

> Check pressure and flow to ensure the fuel delivery system is fully functional. Also check the electrical circuitry and ground supplies. Problems in either area can result in low pressure, causing the pump to run slow.

> Premature failure, fewer MPG and reduced power could be indicators of improper ethanol use, signaling that a repair needs to be done.

> Check fuel level – and make sure your customer does too. Driving on empty can contribute to fuel pump malfunctions. Fuel cools the pump motor, so when running on little to no gas, overheating can result. Besides heat damage, the pump pulls the dirtiest fuel from the bottom of the tank, potentially causing increased wear.

> Check the ground wire leading to the fuel module or pump in the tank on the vehicle side and in the harness for a solid connection.

> Test the fuel pressure and volume and amperage of the fuel pump circuit to help determine the cause of a malfunction.
