Water-In-Fuel Warning

[Cummins2014]

He is a good boy!!!

FYI, just drained the rear filter into a clear plastic water bottle let it run until it stopped only about a cup ,and half looks good to me, if its got water in there its mixed pretty good, I'll let it sit and see if there is any separation, never dealt with this before so don't know what I am supposed to see. I would think the two never mix, so it should be pretty visible in the bottle.

We are in Albequerque, NM today. Tomorrow, heading to the Arizona mountains and desert. It's nice to get out of humid climates (dealing). with the hygroscopic properties of ULSD and all. I never really know what quality of fuel i'm getting. .... Or if an additive will improve the fuel or be a waste of effort and money.

Haven't seen any bio diesel yet, but wouldn't hesitate to use biodiesel in a dry environment. Buying DEF at the pump has not been an issue. The magnet ring helps keep it from turnomg off.

Edit: Lifted trucks ( and Jeeps) equipped to look like rock crawlers that are daily drivers seem to be the fashion out here

Taking a closer look at those wires, they look pretty good ,but I can reach up there ,and feel just a slight void in the insulation with my fingernail, could be enough I guess to case the issue.

 

[Cummins2014]

Not knowing what to look for or what it looked like with water in the fuel, I let the bottle I drained into set for a few hours to see if there was a change .There was none ,so I poured a cup of water on top of it, didn't take but a few seconds for it settle to the bottom, now I know what water in fuel looks like.

Cummins12V98 , I had no water in my fuel, I have an electrical gremlin , or bad sensor ,wires or whatever. No doubt I'll get the warning again in a rain storm. Soon as I can I will change the sensor.

 

[Cummins2014]

Yup Classic drive in downpour and water in fuel light. Chafed wire on rear filter sensor.

Gotta be, it will be replaced. Thanks

I found mine cheap on ebay. It actually came from a dealer

If you don’t believe us......why not start up the truck, then dowse the sensor with a nice stream from a good garden hose?

 

[Cummins12V98]

Yup water is EASY to see in Diesel.

I repeat gotta be , I believe. Thanks again for the pictures. You must of not read the part where I said I have no doubt it will happen again in a rain storm, I believe that’s the part where I believe I’m a believer in yours and others posts

Yup, now I know.

Been lucky enough and cautious enough where I buy diesel, as said to NEVER had water in the fuel, and still haven’t .
I never felt changing that filter was a very good setup as far as wiring , was always careful , but those wires are pretty vulnerable . It’s hard to believe the newer ones have that same filter location and wiring

Reportedly the 2019's have the rear WIF sensor screwed into the base of the rear filter. The rear filter then doesn't have a WIF sensor.

Say that again?

 

[Cummins2014]

He is saying the filter ITSELF does not have the sensor in it , so obviously a different filter. 2019 the sensor is in the base where the filter screws into, anyway thats the way I read it. I guess look up the filter number for a 2019 , and see.
If so, thats a better design, not having to deal with that sensor every filter change .

 

[Cummins2014]

After checking fuel filters for the 2019, its a different filter on the rear as far as I can see , its a cartridge replacement on the chassis. The front filter on the 2019 is the same as ours .

It still needs to be disconnected in order to unscrew the housing. I agree that not having to transplant the sensor every change is nice but I highly doubt that was the cause of early wire damage. It was simply poor design with no reinforcement at the sensor connection. I’ve had no problems since installing the replacement sensor.

Let me ask, what replacement sensor did you buy, replacement OEM is the same as far as I can tell . Wiring appears to not have changed .

Wiring has changed. It is much more robust where the wires enter the sensor assembly.....

Thanks, then I will just replace with OEM. It appears they are are around a $30-40 dollar item.

No reason to replace sensor. Just clean the wires and apply a couple of coats of liquid electric tape and call it good. Did this on my second gen truck and it held up for 15 years.

You OBVIOUSLY totally overlooked the pictures and the link in post #18 I presume?????

It’s only a matter of time before the wires crap out on his....
