Water in Case fuel tank

Michael Price · Feb 27, 2018

I bought a 1070 Case that was sitting for about 18 years in a barn that was falling in. Everything was full of water, aver the last 2 years I still get water in the fuel all the time. Ive drained the tank several times but still get water. I need the tractor and don't have time to pull the tank out and clean it out really good. Anyone have any ideas before I replace all the filters again?

Every time I leave my case outdoors in the rain I get water in the tank. The cap seems to fit snug and the seal is good. I just don't understand how it's getting in there.

Put gasline deicer in your tank to get rid of water, also ATF has an affinity for water, will absorb it and burn it. The ATF also lubes the pump.

good lord turned water into wine...nobody can turn water into gas or diesel...water does not burn

Since its made from oxygen and hydrogen it actually will, if you get it hot enough.

I've never had an issue with water in the tank on those. Have you checked for a hole in the top? Is it the plastic or steel tank?

Crazy Horse · Feb 27, 2018

Jon ......... that's interesting. How "hot" does water have to get so as to separate it into oxygen and hydrogen? I'm assuming that's what you are referring to with regard to heating it and then burning the two components? I would suggest that it is a more complex process than simply heating.

Do you keep the fuel tank close to full or is it always nearly empty? An empty unsealed 50 gallon tank will breath fresh air in and out with each temperature change.

Can you park on a side hill with the water trap as low as possible when you try to drain off the water?

Janicholson · Feb 27, 2018

If you have drained the tank with the fitting at the bottom out, there should be little water remaining. Using Ethanol fuel (assuming it is a gas tractor) will absorb the remaining water with a full tank. Jim

Brother's John Deere "B" sat out, and every time it would rain, water would get in the gas. Pulled off the hood, and found that mice had nested under it, on top of the tank, and the tank had rusted through.

I'm not sure, but big time tractor pullers inject water to cool the engine and figure it in as part of the fuel as well. I never got that big into it myself so I don't know how hot that is.

RGMartin · Feb 27, 2018

Is it an early one without a sediment bowl, or a later one with?

In either case, the primary fuel filter should have a drain on the bottom to let water out. If it doesn't, buy a better brand of filter. check daily.

The sediment bowl will need cleaned daily or better too, it will work its way out eventually.

Hi Jon ........ water injection into an internal combustion engine has something to do with cooling the detonation process and solving some problems (see the link below if you have time and want to scratch your head a bit) but one thing it doesn't do is separate the hydrogen and oxygen and make them available as fuel. The cooling effect does apparently have some positive effect on power though. Separating oxygen and hydrogen is a pretty involved and expensive process, I guess a guy could read up on that as well, hydrogen-fueled vehicles have been fiddled with for some time now but one of the big issues is getting the hydrogen, and it might even come from water I think but it's not easily obtained. A Canadian outfit called Ballard Power Systems makes hydrogen fuel cells and was once thought to be the answer to all sorts of things but so far, still pretty limited production and availability.

Jon ..... that Ballard outfit was a pricey stock 18 years ago, well over $120 per share. Now sits at about $3.50 so whatever technology they developed, things haven't taken off for them much in all that time.

Case never built a gas 1070. Geeze.

The way i understand it on pullers is water is injected into the intake air, a little before the turbo to cool it but mostly after. This is done after the engine reaches a certain amount of boost. When it hits th e engine it gets hot enough to create steam which increases compression, then as the fuel burns it gets hot enough to utilize the oxygen and hydrogen. I'm not sure on the physics, but that is what was told to me.

You better do some visual inspection of the top of the tank. It is fiberglass and not prone to condensation as much as steel tanks are. You didn't say if it was a cab tractor or not, but I would check the fuel gage unit on top of the tank to make sure it is not rotted out. That will take some time, which you said you didn't have!!, but I guess you have time for down time.

Actually, water is the product of burning hydrogen and oxygen. Can force the reaction backwards but energy expensive.

JD Seller · Feb 27, 2018

I have actually had more issues with the ploy/fiberglass fuel tanks and condensation. If your leaving the tank lower on fuel it will slowly gain some water. Like some other poster have written, drain the fuel filters daily before each use. You should get ahead of the water over time.

If the tractor is setting outside and gaining water I have seen a several of the Case 70 series tanks have cracks in the top of the plastic tank after all these years. The top is usually settle into a kind of convex shape on the top and then cracks in the bottom of the "bowl". I have personally replaced/repaired two 1370s , one 1070 and one 1570. That is four and I do not work on many Case tractors. It does seem to be worse on the ones that have set outside in the sun light. Maybe the UV rays have deteriorated the tank material???

Michael Price · Feb 27, 2018

I put high quality filters on it, one has a drain and I drain is often. There is also a glass sediment bowl that catches water too. The glass bowl will have water every single time you run it. I will double check again for cracks in the tank.

I did try some heat antifreeze that is supposed to remove water. I dont think it helped much. Maybe Ill try ATF and see what that does.

It has sat low on fuel often so maybe thats the issue. I live by lake michigan so humidity and condensation happens alot.
