Well Crap

I got my truck fixed on Thursday delivered yesterday picked a load to go to florida and I get this warning.

Oh and my driver side step skirt is loose. Luckily I'm at the terminal so hopefully they can fix the problem quickly tomorrow

Did you pop the hood and take a look at the fuel/water separator and the filter element? It's on the left side of the engine, near the frame rail. On a Cummins, it's near the firewall. On a Detroit, it should be just above the steering gear box.

There should be a drain valve at the lowest point under that. If the filter looks black, that's bad. If there is a visual level of fluid more than 1/2 way up on the outside of the filter, as it appears through the clear plastic cover, it needs to be drained into a clear container. This is what you save those washer fluid jugs for. It's a simple valve....Open or Closed. One quarter of a turn in one direction. Drain it into that container, then have a good look at it. The diesel fuel will rise to the top; anything else will be on the bottom of the mass. The water separators should be drained at least once a week, at a minimum.

Nowadays, with a company truck, only two things will cause water in the tanks: bad fuel from a truck stop, or sabotage. Hopefully it's just a faulty code.

Please, please keep us updated on this. I can't remember this subject ever coming up on the TT site. I would be highly interested in the cause and outcome.

For some reason I seem to get a water in fuel warning almost every time it rains REALLY hard. I push the OK button to clear it and it goes away until next time it rains hard. I drain fairly often and it never has water or any debris to speak of. I don't know I tell ya.

Not a truck but had a JD 4 wheel drive that had that happen often. The water sensor in the bottom of the filter housing was in a place that very little water in the sensor would cause the light to come on and need to be drained.

Mike B! Thanks for posting this problem/warning light. I have driven many diesel stake bodies and light dumps and never came across that issue.

Thank you Packrat for the in depth explanation on how to find, check for and drain the filter on different engine types. Still learn something new here everyday!!!

Well the shop said it would be an easy fix but....im way over due for a oil change so im at the hotel for the night.

ANY UPDATE?

Had that with last truck, after filling up at the TA 0n I-80 in Wyoming...... Was the main fuel filters plugged up, and it was serviced 2 weeks prior, got em changed problem solved

I was gunna drain that separator, but maintenance routed us to a Gardner's shop in Washington, a week later

Ok so they fix the water in gas. They do the oil change on Tuesday. I take it to the body shop to get step and batwing fixed, when i get to my truck after thats done the battery is dead. Had to wait till Wednesday to get it charged then as soon as I hook up to my trailer the check engine light comes on...back to the shop. I finally got out of Nashville Thursday. I did get alot of compliments on how cool I was about it. I just told them its not the companies fault all this happened at once. At the point of the check engine light I just started laughing. Because had to go back to the shop and say you are not going to believe this. I mean I didn't get the load t-called on me which really surprised me since it was a high value load that was due last Sunday. I still got the miles because im here in JVILLE Florida now.

And now you know....the rest of the story.
