A: The engine serial number is on the data plate on the timing gear case on the driver’s side of the vehicle. It is eight digits long and should begin with a 56 for Dodge vehicles.

A: Codes do not definitely tell you that an injection pump is bad, but rather act as a starting point for diagnosis. After a code is read a mechanic can perform additional tests to determine the injection pump is bad. You may also have a pump sent in for inspection and tested on a test bench.

A: The stock lift pump we have is the original pump that mounts on the engine (not to be confused with the Dodge in-tank retrofit). FASS offers a direct replacement pump that mounts on the side of the engine (DDRP) in addition to high performance fuel pumps that replaces the stock system. They are available in a number of different options (either a pump, single filter option, or a system with a fuel filter and water separator). Please contact a customer service representative to help determine which option is right for your vehicle.

A: We are a Bosch Authorized Four-Star rebuilder and have trained technicians who rebuild the pumps at our Bolingbrook, IL location. All of the electronics, the housing, and the piston are replaced as well as any other parts that are damaged or show signs of wear.

A: The VP44 pump comes with a one year-unlimited mile warranty as long as you replace the lift pump. Also, tampering with wires can cause premature pump failure. If the wires are spliced, tapped or cut the pump is not warrantable. Please see our full warranty policy by clicking here.

A: The core policy can be viewed by clicking here.

A: This is a common mistake. If the part that you are holding in your hand is much smaller than the Marine Injector and have not pulled the valve cover you are most likely looking at the injector connector tubes that connect the metal Fuel Line from the VP44 injection pump to the actual injector. Please pull the valve cover; the injectors are beneath. If you have removed the valve cover, please call us with your Engine Serial Number and invoice number to confirm you have the correct injectors for your application.

A: The first number represents the model or series. The HPFP is only the fuel pump. The 95 series and 150 series are both complete systems with a fuel filter and water separator attached. The 95 series has a smaller base with smaller filters, while the 150 series has a larger base, larger filters and more readily available aftermarket filters. The second number represents the gallon per hour flow rate of the system. The number after the dash reflects the specific application that the system is designed for.

A: Traditionally the 95gph system is for stock vehicles to moderate horsepower upgrades. This would be commonly be used for vehicles under 500 horsepower. The 150-200 GPH is for moderate to extreme horsepower upgrades. This would be used for vehicles at 450 horsepower or above. Please contact one of our customer service representatives with any questions concerning your specific application.
