Water in Fuel Sensor - Diesel Forum

SPORTSMAN13 · 01-12-2011, 11:43 AM

I have read all I can find on this subject, but I am still confused. I put 5 gallons of what I thought was good fuel from our agriculture tank in truck just to get home. WIF light comes on with in 3 minutes. I drain lower filter housing using the plug, no difference. I have done this 10 times. I do not see any water in glass cup. Have refueled and added additive. Still WIF light comes on exactly 2 min 13 secs after starting. Disconnected batteries and waited 30 min. No difference. I am going to change both fuel filters and check sensor. How do I check sensor? Can I do it with out removing assembly from inner frame rail? Can I replace sensor without removing assembly from frame rail? Never have had WIF light on before.
Thanx in advance!!

Never add fuel to these trucks that you think may be good fuel, that will kill these injectors just hope it is just in the HFCM and does not make its way to the injectors. This may help
Service Points - HFCM and Fuel Filters

Don't know never had to remove mine but i think all you have to do is remove the one end and clean it i think with brake kleen, if this is wrong someone will have the right answer for you.
