Fuel Problems

[weldon99]

I have a 97 F-350 Powerstoke, crew cab. Call it "The Great White". I am having some problems right now with my rear fuel tank. The truck set for awhile without getting run too much and now I can only get down to about 1/4 tank on the rear tank before it starts running rough and losing power. I've tried putting some additives in but doesn't seem to help much. Anything special to pull the tank off? It probably has some water in it would be my guess.

I bought the truck used (less than 1 year old and less than 20,000 miles on it). It has 140,000 now and the only thing I've done is a brake job, changed a relay, and had the bands tightened on the transmission. This is the first problem I've encountered. Man I can't beleave it, I though Ford would hold up better than this !!!! Seriuosly, it's been a good truck and I really feel like it's just getting broke in good.

Any help would be appreciated.

If it sat for a while with less than a full tank of fuel, it could have easily condensated and got water in the bottom. I would try using an additive called HEAT to remove water...make sure its for Diesel applications though.

Tried this, didn't work. A buddy of mine told me thaqt sometimes the water will form some kind of slime in the tank and it takes a special additive to clear it up, but He couldn't remember what it was called, just that it was very expensive. Not to worried about the expense, just want to get it cleared up. I haven't tried to look in the tank yet. I guess I may just have to try and pull it off and see what happens.

ahead and pull it off.

Here is a link to instructions for removeing the tank, while you have it off anyways, you might want to check out the mods you can do yourself to the tank. up top of the page hit search and check out the harpoon and the hutch mods.
