Running Rough

[cj41foley]

This morning I was almost to work when my truck started running rough, like it was only running on half the cylinders. I looked down and my fuel gauge was at about 1/8th a tank, I normally drive till my fuel light comes on, I eased over to the gas station and got some good ole diesel fuel (1st I've bought in almost a month), put $20 bucks in it and paid for it, left it running and came back and revved it up a few times and then it cleared up, drove fine the rest of the way to work. Maybe just almost out of fuel? Maybe some water in my tank? Maybe I need to change my fuel filters, they've got 18,150 miles on them! My water in fuel light is not on and I know it works because it came on right when I first bought my truck, I drained it from under the truck and the light has not came on since. ???? Maybe I'll just drain it again when I get home, I mean it's only one plug, can't hurt nothing.

First thing I would do is change the fuel filters. The book says do them every 24k but sound like your fuel stays in your truck for awhile b4 the next fill up. I do mine evry 12K. Maybe also cleaning your EGR valve would help also.

Diesel fuel doesn't have near the life span as regular unleaded so I would try to fuel up a little more often and one of the worst thing you can ever do is drive until your fuel light comes on. My wife does that and pisses me off.

Doing that is pretty bad on fuel pumps because the pumps are cooled by fuel.

Oh no, I burn a tank of fuel per week, I've been running bio diesel and have'nt bought regular diesel in almost a month. Been running the bio diesel in our tractor, Kubota rtv 900 and my brother's and father's cummins and no problems with any of them yet, so I don't think it's the bio!

10-4, I've been meaning to do it. How much does the 2 filters normally cost? I know one is on top of the motor but where is the 2nd filter?

[slammedSI]

they run about 45 bucks from advance auto parts, We carry 3 different brands, But im sure you can get them anywhere. I would stick with Motorcraft if you can get it.

[cj41foley]

aight, preciate it, I usually shop at Advance anyway, I'll probably stop in on my way home and get em'

I was going to say filters too since you've been running the bio... but why would it come back and run fine just because you put dino in it?
