Tools needed:

See the parts list for 00-01 Diesel fuel filter number

See TSB 14-02-00 for cover removal cautions, and TSB 14-03-00 for details about cleaning the WIF sensor.

Place a bucket under the water/fuel drain hose that drops from the filter housing. Note: An extension tube slipped onto the end of the factory hose will help direct the drained fuel into the catch container with less mess. Without an extension, fuel will puddle on the 4X4 front axle and leave a trail when you drive away the first time.

DO NOT turn the cap using a socket wrench extension in the square hole in the cover (early models).
Use a 1-1/8 " six point socket on the fuel filter housing cap's hex casting to loosen the cap.
When the cover starts to spin freely, open the water drain valve by lifting the drain lever. Leave the drain open and your fuel-catcher in place.

Have a big zip lock or plastic bag ready for the filter and the filter housing lid into so you don't spill/drip fuel all over the engine.

Gently pull the filter housing lid up. It has the filter attached to it via snap clips on the underside of the lid. When the fuel filter is almost out of the housing, procede slowly and gently wiggle the top assembly until te filter pops out. If you will pull to quickly, the filter will pop out and spill fuel.

When you pull the filter completely free of the housing the seal will be broken and a lot more fuel will dump out of the filter itself. If you successfully pull the filter straight up, this fuel will dump harmlessly into the housing, through the drain and into your catch-container.

Use the bag to transport the filter and cap out of the engine bay.
Use a clean, lint free cloth to wipe the inside of the housing. Clean the WIF probes inside the canister housing as instructed in TSB 14-03-00.
Turn the whole thing upside down and you will see how the filter is held in place on the lid. Pry out the old one and pop in the new one, making sure to replace the big o-ring on the filter housing lid. Lubricate the o-ring with fuel or oil.
Close the drain and fill the filter housing with diesel fuel leaving enough room to get the new filter in without overflowing. (NOTE: I put mine in dry and bumped the starter seveal times to prime the system) Thread the lid and filter back into the housing. Proceed slowly and do not use a wrench, it is easy to cross thread the plastic lid.

Torque the lid with the socket and torque wrench to no more than 25 ft-lbs (Cummins says hand tighten).

Turn the key to the run position. Bump the starter for a millisecond and let the key stay in the run position as if you had actually started the engine. You will hear the lift pump cycling for about thirty seconds, which will circulate fuel and push any air in the system back to the tank. Bump the starter several times, allowing the pump to cycle each time, then attempt start the engine.

If the engine starts but then dies, bump the starter several more times and allow the fuel pump to run until it stops each time. After several cycles, attempt to start the engine. Repeat the process until the canister is full and the engine starts and runs. With a dry canister, I cycled the pump three times, then started the engine. It promptly died and took seven cycles of the starter and fuel pump before it restarted. If the engine still will not start, try several cycles of cranking the engine for 10 seconds and allowing the pump to run after each crank attempt. As a last resort, bleeding the fuel lines may be necessary. Begin at the filter and continue along the fuel line to the injector pump until all air is purged. Torque the banjo bolt to 18 ft-lbs.

Filter Information from Cummins:

A new Raycor fuel filter element must be used with the Chrysler ISB application. Use the Cummins chart to determine the correct fuel filter. The new 2 micron filter must be used on Chrysler ISB applications and is backwards compatible with pre-ISB Chrysler engines.
