As most of you that own and drive 98.5-02 24 valve 5.9L Dodge Cummins equipped with the Bosch VP44 injection pump already know, the VP44 is extremely susceptible to failure caused by lack of fuel supply. This is due to the inefficient factory fuel pump's frequent inability to supply fuel to the injection pump. Until 2005, the factory lift pumps were mounted on the side of the block behind the fuel filter. This caused the pump to absorb a lot of heat and also required the pump to "pull" fuel, as opposed to "push" fuel, as it was intended to do. Years later, Dodge recognized this issue, and began selling update kits which involved a new pump that got installed into the fuel tank. This is a better alternative, but still not a suitable replacement for those seeking longevity or are increasing the fueling demands of the truck through chips, injectors, etc. We offer lift pumps from FASS, PureFlow AirDog, BD, and numerous others, as well as popular accessories such as the BD Low Pressure Warning Light, BD VP44 Stealth Cover and ISSPRO and Autometer fuel pressure gauges.
We also sell a variety of VP44 Injection pumps to cover stock trucks to highly modified trucks. Whether you are in the market for a 235HP, 245HP or a Hot Rod VP44 we've got you covered. We also carry stock and performance injectors from Dynomite Diesel, BD Diesel, and Industrial Injection as well as filtration solutions from Glacier Diesel. If you don't see what you need for your VP44 equipped truck please give us a call and we will be happy to help you find it.
Note: If you own a 1998 Dodge Ram Cummins, you may have actually have a 12 Valve or a 24 Valve Cummins engine, and it is VERY important to know which engine you have, if you do not already. The easiest way to check is the factory badging on the front doors of the truck. On 12 valves, it will read "2500" or "3500" and directly below that, it will say "Turbo Diesel." On 24 valves, it will still show the "2500" or "3500," but will say "24 Valve Turbo Diesel." If the factory badging has been removed, one can also tell by inspection of the valve cover. A 12 valve will have six separate valve covers, and a 24 valve will have one solid cast valve cover.
