89-02 Dodge 5.9L Cummins PDP Fuel Filter Kit

89-02 Dodge 5.9L Cummins PDP Fuel Filter Kit




*Unless you use the vehicle in continuous 10ºF or less temps this is not required, though proper fuel treatment and using reliable fuel sources are highly recommended.

*The snubber is to maximize accuracy of the sensor/gauge and protect them from injection pulses which will be noticed as needle bounce. The plug is needed if you do not plan to run a gauge.

If your truck did not originally use a spin-on filter you will need a WIF sensor unless you plan to run the sensor-less FS19608 which has a built in drain.

Contact us if you would like another of our options.

Recommended for applications over 350hp, for applications pushing more than 600hp see our pn:PDPFLAK to compliment your filter head.

Though these are commonly reusable, over tightening can cause them to leak. Avoid the headaches and get a new set, tighten as if you're spinning an 8mm bolt.





This is Pure Diesel Power's CNC Machined Fuel Filter head designed for the 89-02 Cummins 5.9L. This fuel filter comes standard with a port for a 1/8" NPT fuel pressure sensor to work alongside your fuel pressure gauge. A 1/8" NPT plug comes standard with the kit if you do not have a gauge for fuel pressure. This kit is designed to exactly fit your 94-96 Cummins without any modification, with slight modifications will work on 89-93 Cummins (bending/positioning lines) also 97-02 may require modification to the end of the fuel lines to fit if they have ever been updated to the plastic lid cartridge filter. Our fuel filter head is CNC Machined for added strength and durability over the stock housing. This kit is the perfect solution for your leaking fuel filter or if you're upgrading your trucks performance/looks and simply prefer a spin-on filter. With our optional Banjo Bolt upgrade, you can protect yourself from snapping a weak bolt in addition to getting a higher flow for your high-performance vehicle! Also, add a Fuel Pressure Snubber to eliminate fuel pressure gauge "vibration". 


Due to having to spin the fuel filter to change it, it is highly recommended to have a plug-in style connection for the water in fuel sensor. Unfortunately, after extensive searching, we are unable to source a plug that mates with the factory water-in-fuel sensor. The next best thing was to source a quality, weather-resistant male-female plug kit.

Thanks to PDP for making this obsolete part. It is a great upgrade and direct fit along with enhancing the looks under the hood! Great Job PDP!

I bought this with a sandwich heater this summer and it has worked great so far up in Alaska. I bought my truck knowing the stock heater was inoperative and this was a great solution for me.
