How to purge air from a cummins 24 valve diesel fuel system

I drained to much fuel out of the fuel pump while removing water from the pump. I refilled the fuel pump with negative results trying to start the truck. The truck is a 1998 Dodge 1 ton dually

Any help would be greatly appreciated!

Is it an electronic engine or the boch inline fuel pump? They chaned half way through 98. If its an inline pump there is a hand primer on the fuel lift pump on the side of the engine, just keep pumping it until you hear the relief valve on the injection pump hissing, it should start then, if not loosen a couple fuel lines at the injectors and turn it over a few times to bleed the air from the lines.

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.

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.

The fuel system needs to to have the air bled out of it. I suggest having a technician do it for you to prevent serious injury and damage to the vehicle.

Have a 2011 RR Sport Diesel. incorectly put 2 LTRS unleded fuel defore cut out activated.Used the reset tool provided & filled the tank with Diesel Intend on continually diluting on a regular topping...

You must drain and refill the fuel tank. Some of these systems use optical sesnors in the injection pump and can be damaged not to mention the damage to the pistons and valves. Great trucks. Drain the tank.

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.

Hi, I own a 3.0 d4d toyota fortuner (same engine as 3.0 d4d hilux) and as of yesterday it started belching white smoke. it starts and idles perfectly fine, the exhaust just smells off. not like unburnt...

White smoke on diesel engines, means water in combustion chamber. Blue smoke means oil.
In what condition was the filter you removed? How bad? Temperature issues? Missing coolant maybe? If yes, you might as well have an internal leak. Some gasket maybe. Check all you vital fluids levels. If anything missing, take the time to empty the engine oil on a can, and check the colour. If it will look like chocolate brown, then you do have a leak from the inside.

A diagram for changing the water pump on a 2006 dodge ram 3500 cummins diesel

On a cummins turbo diesel the water pump replacement is quite simple i do believe. just have to remove the belt. The clutch fan, and pulley, then the water pump is right there i believe being held on by 4 bolts only and remove. Remember to place the wate pump o-ring on the water pump and hold in place with sort of adhesive just to make sure it doesn't slip out during installation or this will cause a leak. Once everything is installed then you will need to purge the cooling system of the air bubbles by letting it run and watching when the thermostat opens up. You can tell because the level will drop in the rad or over bottle, depending on what controls the fluid. Let it open two or three times, and go for test drive, all should be well...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
