puffs at high idle

Crog · Mar 14, 2003

I have been looking at diesel fuel treatments on line, and came across Kinetic K-100-D. As described, it emulsifies the water in the fuel so it can burn through, kills algae and cleans injectors. It is about $20 per quart. Has anyone had any experience with this product?

There was both water and algae sludge in my fuel filter when I cleaned it out. I am going to replace the filter itself today. I have no objection to draining the tank other than that I don't know of a good way to dispose of the old fuel.

I am open to suggestions regarding any products that are good for dealing with water and algae.

FYI,

Spent most of the day Saturday troubleshooting over the phone with Bill of Barnett Tractor Co. which is where I bought the Hinomoto. He has been very helpful and patient.

Unfortunately we narrowed it down to a problem with the injector pump. We hoped it was just the timing, but I removed a shim to no avail. The problem is getting progressively worse.

The good thing is that Bill gives a 6 month warrantee on the gray market tractors he sells, and he is going to have the pump rebuilt for me. I'm shipping it off tomorrow.

Thanks for all the good advice.

I don't know anything about that brand of fuel treatment. But I do know that I like PowerService. I use about 450-500 gallons of diesel a year and I have not had any kind of fuel problems since I started using PowerService.

<font color="blue"> diesel fuel treatments... is about $20 per quart...</font>

Even at a current high price of $2. / gallon... Ten gallons of diesel fuel seems to be a much wiser and better choice... vs. $80. / gallon of questionable additives...

I use 911 diesel treatment. One 10 dollar jug treats 200 gallons of fuel. It does not contain injector cleaner in it. The best way to keep injectors clean is to not run dirty fuel through them and run the engine under load with as little idling as possible. Once they are dirty either rebuild or replace. I sure would have treated the diesel for water before I rebuilt an injector pump. But hey it wont hurt /forums/images/graemlins/grin.gif

Thanks,

I am going to drain the tank completely tomorrow and go get some fresh diesel to try it out. The pump is out right now, but it is easy to put back in.

I will have to be sure to bleed the air out of the system well. What are the indications that there could still be some air in there? Will it idle rough, smoke, etc.?

Be sure and inspect/clean the inside of the tank thoroughly. Green plantlife tends to grow in there if there was water. If you have air in the system, it won't start.

"Will it idle rough, smoke, etc.? "

It won’t start period. It is almost impossible to get all the fuel/water out of the whole system so you will want to treat the new fuel also. This is a common problem we see everyday. They come from Japan where they are soaking wet and the farmers are not careful about how or what fuel they put in. If you can get a rebuilt injector pump out of the deal I would go for it. /forums/images/graemlins/grin.gif Just curious was the oil low or old in the injection pump?

I went ahead and drained all of the fuel from the tank. As the last of it was draining, there was quite a bit of water that came out with it. When it was about empty, I shined a light in the tank and could see some white milky stuff draining out.

I went to a 24 hour truck stop this morning and got a fresh tank of fuel. I added a little to the tank on the tractor as it was draining to try to get the rest of the water out. I really tried to remove the tank to clean it out thoroughly, but could not get it out. The steering wheel has to come off to remove the sheet metal that all the gages and such are attached to. I must not have the right tool because I could not get the wheel off.

Anyway, I put in a new fuel filter, reinstalled the pump, and filled the tank about half way with the fresh fuel (no additives). Runs smooth as silk at all throttle settings.

Obviously water is the culprit. I just don't know if the water was in the fuel I added, or if it is water that cannot be removed from the tank. Could be that when the fuel gets near empty in the tractor, it pulls more of the water in with the fuel and jams up the fuel filter. That would not explain why I still had problems on Saturday after replacing the filter. Hopefully it was just a bad batch of fuel.

Thanks for your help. I'm really glad I stepped back and tried this before sending in the injector pump.
