Driving home today in a downpour and about three miles from home the "Drain Water/Fuel separator" indication came on. In the pouring rain, I crawled under the truck and flipped the lever - Nothing came out! I stuck a piece of 200lbs monofilament fishing line in the drain hole in case it was plugged with road grime - still nothing came out.

I then restarted the truck to have not only the "Drain Water/Fuel separator" indication come on but now I have the "Wrench" indication!!

I have already called the dealer and will be taking it in tomorrow. I have been buying my fuel at the same BP station for the past 6 years.

Anyone had similar indications or problems?

Thanks in advance,
Tawn

 

I haven't had the problem you described but if nothing come out when you drain it she's probably filled up with some nastiness, paraffin, algae, something. Have you been draining it regularly?
You should get a nice stream whenever you drain the separator.

 

I'm not going to lie...I have not been too religious about it - the "Drain Separator" light has never come one before but I have been very strict about the 10K fuel filter changes.

What has me concerned is that the wrench indication came on after I tried to drain it. The truck has 83K and is stone stock.

 

you will need the fuel/water separator cleaned out. New fuel filters.

Hope that takes care of it.

Be sure to shine a flashlight in the fuel bowl and check for metal fragments. If present then you will need the fuel system cleaned and probably a new HPFP.

Lesson learned, take care of your fuel system.

 

Probably just plugged up with crude, hopefully not a big deal, do you run a fuel conditioner, that would help also.
You really need to drain the separator once a month, I do mine more often than that and run optilube XPD as a conditioner.

 

I got lucky. The separator drain was just plugged up. Cleaned it all out and changed fuel filters and it appears all is well.

 

Thanks for reporting back! I try to drain mine once a month but its tough....I only put about 6,000 miles a year on mine though.

 

You dodged a bullet there. Drain at least monthly, more often if you suspect bad fuel.

 

Maybe not! Today the DRAIN WATER SEPARATOR and the WRENCH lights came back on. The engine turns RPMs but doesn't make any power. I drained probably a half gallon out of the separator with no change in symptoms or indications. Going back to the dealer Monday.

Are these the symptoms seen from HPFP problems? What should I expect to hear from the dealer Monday afternoon?

Thanks,

metal in the fuel bowl.

 

On the water separator?

 

check the engine mounted one for metal.

 

Could be the sensor is bad rail mounted pump, or it may be gummed up. You can always pull the upper filter and look for fine particles of metal as Senix says, I tend to think it's a one of the other issues but you never can tell.

 

It could just be the sensor but with the wrench light...I just don't know.

I'd have them or you buy a sensor and see if that works. Still need to check that top mounted filter.

May not need to change it but I'd pull it myself and have a look.

Rust or metal and then you are done. Shine a light into the bowl.

 

K...thanks guys. I will report back.
