Where is the fuel filter located on a 2007 6.7L dodge ram 3500 diesel pickup truck

Removal and Installation of the Cummins 6.7L Fuel Filter/Water Separator Mopar P/N 0518341AA

Job Time: 15 minutes
Tools needed:
5/16 Nut driver or Ratchet and socket
1/2" Drive Ratchet with extension for filter removal
Strap wrench
pan or jar for Fuel Drain
Motor oil

Got out there today and changed the Fuel filter and here's how I did it.

From the drivers side of the truck remove the (8) 5/16" screws from the fender liner and there's also a clamp attached to the fender liner by the brake fittings that needs to be pushed out and then remove the liner exposing the filter.

Wipe off all the dirt and junk from the filter, disconnect the Water In Fuel
(WIF) connector from the bottom of the filter and then place a drain pan below the drain valve and then open the drain valve two revolutions to drain the fuel from the filter. ( I used a mason jar stolen from the Queen so I could look at the drained fuel)

Now you have two ways of removing the Fuel Filter. You can either use a 1/2" drive ratchet inserted in the the bottom of the filter (You can't turn the filter the wrong way because the opening for the ratchet will only allow you to remove the filter this way.) or you can use an oil filter or strap wrench as I did.

Make sure when you remove the old filter to remove the drain hose to use on the new filter and you'll also have to reach up into the fuel filterhead/Housing assembly and remove the old end seal but it can be thrown away.


Install the yellow o ring that comes with the Filter and make sure the above end seal is installed.

Lubricate the O-Ring with clean engine oil. (Do not pre fill the filter with fuel or you'll toast your fuel pump.)

Install the filter until you feel it contact the head and then turn 1/2 rotation more.

Install the WIF connector and drain hose.

Prime the engine.
1. Turn the key to the RUN position but don't try to start the engine for 20 seconds.
2. Crank the engine for 1 to 2 seconds. If the engine does
not start, then release the key or starter button back to the
RUN position (do not turn the key back to the OFF
position). The electric fuel transfer pump will continue to
run and purge air from the system for about 20 seconds.
After 20 seconds, attempt to start the engine again.
3. Repeat the procedure if the engine does not start.
4. Start the engine using the Normal Starting Procedure and check for leaks.

Reinsert the wire clamp into the fender liner and install the fender liner with the (8) 5/16 bolts removed earlier and Congrats you're done.

I took the filter apart and here's what my filter looked like after only 8800 miles. So when the Master Tech I bought lunch for so I could pick his brain told me that the best advice he could give any Cummins owner is to change the fuel filter at least every 10,000 miles he wasn't just blowing smoke and that was the best $10.00 I've spent in a long time.

Bmw diesel wont start

I'm guessing that you got an air lock in your fuel system as a result of your changing the fuel filter... I certainly don't know about a BMW diesel, but in most semi-truck engines, there is a priming pump just for the purpose of getting the air out ... and the fuel into.... the fuel system. I've even been known to fill the filters with diesel fuel before screwing them onto the base.. This is risky because of the possibility of allowing some foreign, unfiltered debris to get into your pump and/or injectors, just because of your putting unfiltered fuel into your filter... Check and see if there is some kind of priming pump close to the filter. Also, a possibility is that you may have an electric fuel pump.... as to where all you may need to do is loosen a fuel fitting on the pressure side of the pump and filter.... and allow the electric pump to purge the system of air.. I confess to my lack of knowledge on your BMW.... but, I do have some basic understanding of most diesel systems... Good luck..

Where is fuel filter location on 2001 bluebird shuttle bus with 5.9l 24v cummins?

the diesel fuel filter should be located on the firewall and should be a spin on/off filter like an oil filter and must be filled with diesel fuel before installation. if you go buy the new one first it will help you locate it on your bus

I ran a mixture of diesel and water thru my fuel system about three miles or so what do i do now

drain the fuel, change the filter, add fresh diesel. cycle the key several times and see if she fires up. you might have to crack the injector lines to help in bleeding the air out of the system. the good thing is the vp44 injection pump doesn't know what its pumping and 2001 24v cummins do not have electronic injectors, so you should be ok.

My 2002 Camry is starting to idle so low that it dies ocassionally

Your car probably requires a comprehensive engine tune up.
During engine tune up mostly three areas are addressed:
1. Restoring the cylinder compression.
This system requires the adjustment of valve tappet clearance at operating temperature.
Inlet=0.25mm-0.30mm, Exhaust=0.25mm-0.35mm)
2. Servicing the air and fuel system.
Servicing and inspecting the throttle body, ISC (Idle speed control valve), element air cleaner and MAF ( mass air flow sensor)
Fuel pump pressure approx. 38psi - 44psi.
3. Servicing the ignition system.
Inspecting and/or replacing/adjusting the spark plugs gaps(0.9mm-1.1mm), igniters (visual inspection)

I need step by step instructions on replacing a fuel filter in a 1998 gmc 6.5 turbo diesel please

I got this from Haynes Diesel Engine Repair Manual. I bought it for my 6.2.
1. Remove the fuel filler cap and air cleaner assembly.
2. On filters without an air bleed screw, place a rag under the filter to soak up fuel and detach the lower clip FIRST to release pressure and then the top clip. They pop off with a screwdriver.
3. On filters with an air bleed screw (top passenger side) drain fuel from the filter by opening the screw first and the engine water drain valve (engine front near thermostat) if it has one. Detach the clips and remove filter.
4.Make sure the seating surface is clean and place new filter in position. On non-air bleed filters put the upper clip on FIRST. On air bleed filters secure both clips, then close the valve and attach a piece of hose to the bleed port into a pail.
5. Air must be purged BEFORE start up, so disconnect the pink wire from the top of the injector pump and crank the engine in 10 second cycles with a 30 second wait time until clear bubble-free fuel comes out the lower fitting or air bleed. Connect the lower clip on the non-air bleed , close the bleed hose and reconnect the pink wire.
6. Start the engine and let it idle for several minutes to purge any remaining air and check for leaks.
Hope this helps.

Truck wont start after draining fuel filter?

You may have gotten air in the fuel lines. Diesels cant deal with this as well as gas engines should be a purge / bleeder valve on the fuel lines to eliminate the air. may cough and sputter for a while
