Need input ASAP please, "Water in fuel"

[helievacpilot]

Sorry, I don't have time to search, but my wife just called from the road. She's currently driving the 96 quad cab dually we just bought in FL back here to PA. She's driven about 150 miles on each tank and got a "water in fuel" light for about 45 sec. when she switched to the rear tank the first time. She said there was a very slight intermittent hesitation at times. She just filled up and switched over to the front tank and the light is on again. Once again, it is still running, but with a VERY slight hesitation. Do these truck have a water filter? Is the light indicating that it's full? I told her to stop and put some diesel gas treatment in each tank and see what happens? Anything else I should be telling her? Thanks for the timely responses.

i believe there is a way to empty the water seperator or something of the sort. i am not 100% positive. i would have her put some Diesel 911 in it. its a red bottle you can find at any truck stop. might help it

[helievacpilot]

I'll pass that along to her. Thanks.

[thesmokinstroke02]

your welcome, hope it helps!

She just picked some up, so we'll see what happens. She calculated about 14mpg for each tank. It's also possible that the truck has been "chipped", but not 100% sure. Please chime in with any other ideas and I will keep updating as she contacts me.
Thanks again - Bill

Good news so far. She added the diesel 911 and the light went out after a little while. Next fill-up, I'm going to have her put the Power Service "Diesel Kleen" in it for the next run.

If she gets the light again there is a small drain lever just to the passenger side of the round fuel filter cover that is under the lid on the engine cover (if it still has one) dead center towards front of the engine. Open it for a few seconds and close, it should leave a puddle under the front center of the engine on the ground.

Thanks. It seems the fuel issue has been resolved, but now there is a substantial oil leak. When she stopped for fuel, she noticed some oil dripping from underneath. When she checked the level, it was down approx. 2 qts in 600 miles! Holy Crap! She topped it off and has stopped for the night. Not really much she can do on the road. I'll have to diagnose when she get's here tomorrow. Hoping it's something simple, like a pan gasket, but that's usually not my luck. Rear main seal maybe?
Thanks for all the help - Bill

Truth be told I would rather it be the rear main instead of the oil pan. Be sure and check around the pedestal area, could be o-rings or ebpv actuator.

The Turbo pedistal would be a good place to start looking for a leak, but props to your wife for even paying it any attention and trying to find a solution instead of just riding on ha
