Fuel Filter

[Hayman]

This is what happen to me at -25 below i know i should have had power service in there before it got that cold ,so i change the filters & this is what i had.My question is why won't this filter melt back into diesel its like a sludge, I wanted to see how much water was it there but it wont melt down.Its been running fine now,I change filters at 20k & now it has 40k on it a little input would be definitely appreciated.

Just a heads up you should change you filter every 10K. Power Service has a 911 that claims no filter changed is needed, don't know why it doesn't melt back down.

I believe what you have is the parrafin wax on the filter that gels not water.

Man I ain't never seen one that bad before. What are you putting in that thing, raw drip diesel???????? Yup Parrifin

I took a trip and put 1500 hundred miles on it and i am wondering if i pick up a mixture of biodiesel and hi-way fuel.This filter has melted down a little but still got that white film around it.

Wow.............I would wander where you get your fuel from. I mean holy @#$% man.

Looks like aftermarket filters. The OEM little one has a water seperator screen on it.

Supreme said it....Use Motorcraft filters on you 6.0. Now both the new Motorcraft fuel filters have water seperator screens. Perfect example of the continued design changes made to the OEM line of parts to increase performance and reliability. The aftermarket guys are not included in this R&D.
You must have purchased some fuel from a very questionable source. I would try to purchase fuel from one reliable source as much as possible. I have never seem a fuel filter loaded up with parrifin like that dude......

I think you may be right about the bio diesel, I showed that picture to several other mechanics and one of them said he new exactly what that was. It is baseicly LARD, yup cooking oil, he works for a company that uses a type of bio-diesel that they mix diesel and used cooking oil and burn in their tour busses. He said that happens when they mix too much cooking oil to diesel. He sees it quite often.
Just thought I would let you know.
