The FASS DRP 02 Direct Replacement Fuel Pump is a complete replacement pump for your 1998.5-2002 Dodge 5.9L Cummins. This pump is designed to eliminate the common issues found in factory lift pumps that are known for their costly repairs. The DRP lift pumps larger motor is strong enough to help supply your diesel truck with a consistent fuel pressure required by your VP44 to produce efficiency and horsepower. Designed for ease of installation, the DRP series pump can be installed by any novice mechanic and installs into factory mounting points making it the easiest installation of any aftermarket lift pump.

Factory Fuel Pump Failure

Failure of your factory lift pump is one of the most common component failures for the Dodge Cummins 24 Valve diesel engine. Both stock and modified engine suffer from this issue, with modified engine intensifying the weakness of the factory component, leading to premature failure. The main reasons behind this pumps inability to support the fuel demands for your Cummins engine is the fact that first its a smaller weak motor that is located near the engine. This requires the motor to pull fuel from the fuel tank located at the rear of the truck against the momentum of your moving pickup. As with all diesel lift pumps, motors are designed to be push fuel and when required to suck fuel over a long distance the added strain will overheat the motors, leading to a drop in fuel pressure. Low fuel pressures can cause a decrease in throttle response, fuel economy, horsepower numbers and even cause damage to your VP44 injection pump.

DRP Relocation Brackets (Sold Separately)

To help the DRP series lift pump perform to its top potential we have designed an optional pump relocation kit that will move the lift pump closer to the fuel tank, reducing the distance the lift pump needs to pull fuel from and instead places fuel under pressure to push diesel to the engine. This is beneficial because all diesel lift pumps perform better as Pusher pump and when under pressure the motor doesnt need to work as hard to supply the fuel demanded by the injection system. Sold separately, see related items below.

Awesome pump

I installed the DDRP on my 03 when I had it and I had no problems easy install and made my truck run a lot better than stock. The truck was mildly modified and the pump kept up with it. I had replaced the pump two times before getting the DDRP and I wasted my money on the other pumps FASS has a great product and has been in the game along time. Recommend the pump.

Just installed this on my 1998.5 24v 5 spd ram 3500 4x4. Installed easily and my fuel pressure at idle went from 10 to 16.6 psi. Can feel the difference for sure, truck is smoother and a lot stronger, well worth the investment. No regrets with the upgrade, truck is pretty much stock, would recommend to others.
I think not

I installed this Fass ddrp exactly as instructions stated with new fuel filter. It lasted less then 2 thousand miles. Not worth the price in my book!!! I ordered it in middle of winter and did get installed for two months and did not read if the warranty card is not sent in within 30 days no warranty.

Most Popular Questions

Can a Smarty S2G Touch be used with this pump?
View Staff Answer 

The FASS DRP 02 Direct Replacement Fuel Pump can defiantly be used along with the Smarty S2G programmer. (We highly recommend the use of a fuel pressure gauge with all pumps to ensure proper pressure and help avoid fuel system damage.)

Can I use the XDP Sump instead of the draw straw with this lift pump? (I have the retrofitted in tank dealer pump)

Yes, you can use our XDP Sump on trucks with the retrofitted in-tank lift pump.
