filter w/o water-in-fuel sensor

[Squirrel]

Can someone point me to the fuel filter part numbers. I'm looking for the replacement filter without the water-in-fuel sensor. I tried searching, but I can't find it. Thanks.

Fleetguard FS1221. Baldwin BF1221. www.fleetguard.com. www.baldwinfilters.com. Search their catalogs for pics and dimensions of those filters. They are longer than stock, have a drain but no WIF sensor port. 22 micron vs. 25 micron stock. Scheid Diesel carries the FS1221 if you can't find it locally.

Thanks, I'm getting air from somewhere. Only affects the truck when I have my foot in it. The sensor isn't plugged in, so I might as well eliminate that as the problem. I already have new line from the tank to the lift pump. Thanks again.

A very common location for air to get into the system is between the fuel heater (right above the fuel filter) and the cylinder head. There is an o-ring between those two that will get old and brittle. It can be replaced, it's available from the Dodge dealer or Cummins.

Or do what I prefer, eliminate the fuel heater with a shorter filter spud/adaptor available from Cummins for about $17, Cummins part number 3925954. Then the only o-ring/gasket will be attached to the fuel filter itself.

The fuel heater is just an illusion of safety so to speak. If your fuel is gelled in the tank, an engine mounted fuel heater sure ain't gonna do a thing except sucked juice from your battery.

If it only does it when the engine is running, the problem is before the LP. From the LP to the IP it's under pressure, kinda hard to suck air into a pressurized system.

I just replaced the fuel line this winter with a solid rubber line from the sending unit to the lift pump. I pulled the sending unit and it looked OK, so I put it back together. I'm still running the original style lift pump, the truck is all stock, still has the crush collar over the fuel screw. My problem is intermittent, but basically I'm going down the road and it's like you shut the key off, no pedal, but lights, guages work etc.. Drift off the side of the road, I have fuel to the banjo bolt at the filter, and when it's cracked open and roll the truck over it's pumping good, then open injector lines, no fuel, crank it over fuel spits out, do that to all and then sometimes it will start. Other times nothing, leave it sit for 30 minutes and it fires up like nothing is wrong. It happened on Friday with 2 ton of sand on the truck. We got it running, and I made it another mile before it died again. Primed it, fuel to injectors, nothing. Went home ate dinner, came back it fired up without any messing and I drove it the 1/2 mile back home without problems. Since it's started and run fine. Last time it did it was this winter, I blamed it on air and replaced the fuel line, since it still had the original plastic lines. Same symptoms, and it's been fine since, but I probably only put 500 miles on it. My neighbor said to look at the fuel shutoff, if it's not getting juice it could cause the same problem. Is there a breaker, or relay on that circuit that could be getting hot and kicking out, then resets itself..? Any suggestions are welcome, I've been looking at newer trucks because this one has just left me down too many times.

The cost vs. benefit of these things is way too high. For a device that does such a simple task, there's too many things that can go wrong with it. I gutted mine with a punch and BFH, tapped it and turned it into a solid plug - literally.

[seeker1056]

sounds to me like a wiring issue for the fuel shutoff, or a malfunctioning shutoff

Try carryin a jumper wire and the next time it quits hotwire the shutoff solenoid and see if that cures it.

if not i would be replacin the solenoid itself - they are not that expensive

[PToombs]

I agree on a shut off solenoid problem. You can pull the plunger and spring out and see if it still does it.
The 1st thing I would do is carry a test light, if it quits, check for power to the solenoid. If you have power, touch the wire on and off it and see if it clicks. If all seems well, then pull the guts.


Ace, why waste the time to punch it out? Just pull the plunger and call it good. I could see tapping it if you wanted to check pressure there, other wise why bother? I have never seen one leak from the terminal.

[Squirrel]

You guys were right, thank-you, thank-you. I fired it up and tested for juice to see what I had, then I started wiggling wires and connections. It studdered a little, more wiggling and it died. It was the hot wire running to the selenoid, seems like the wire is loose in the connector. They still have the blade connection and were pretty crusty, I'll be switching them to eyelets. What is the other wire for going to that selenoid? While the truck was running I pulled that wire off, and it had no effect, when I pull the hot wire it shuts down immed, just like it did on me last week. Thanks.

Because another one of the things that can go wrong with them that most people aren't aware is they can leak. The plastic insert that forms the solenoid body can become compromised and leak. At least mine did.

I had initially just took out the plunger like most do when they go to the pull cable. That was fine for a few months, until I noticed it leaking. Drove me crazy trying to figure out why until I watched real close up while I started the truck by jumping the starter solenoid with my face in there under the hood and saw fuel start coming right out the top of the dang thing.

I believe that powers the cold start advance device (KSB)

Squirrel, Ross is right, KSB power.

Ace, gotcha!
