Cleaning a tractor diesel tank

Post by Brute 23 » Sun Aug 26, 2018 5:06 pm

We have s JD 2755 and I have been having to blow back in to the tank every so often. Any one have any easy tricks for cleaning out the tank?

Its a plastic tank mounted at the front. I was hoping to not have to take it completely off.

Take it off completely and was out through the filler. Alternatively keep filling allow to settle and siphon from the bottom using the siphon hose like a vacuum cleaner.

Drain the tank, pour a little diesel back in trying to stir the bottom. Pressurize the tank with a rag and air hose to push the gunk out. Repeat till it looks good.

Their is a drain valve in the bottom of the tank. However I don’t remember how easy it is to get to. Just draining may clear the gunk.

Thanks. Im trying to finish up a few things before I tear in to removing the whole tank. I poured some stuff in the tank, ran it a couple days, and pumped it out with a big sprayer pump and a 1/2" hose.

I replaced both filters and used a clear one for the in line filter so I could see what its catching.

Have yall taken that fitting out of the side of the tank that holds the down pipe and float? Is it just a half turn deal and it pulls out? Guessing it has a gasket of some sort behind it?

Hind site I should have unscrewed that whole pick out when it clogged and then blew it out on the ground. The way I did it I blew what ever was in it back in to the tank.

you'll get the best results by removing it completely and ideally you'd steam clean it, though a pressure washer could do the job

Agreed and also run a can of biocide through it once a year. The chunks/gunk is probably algae.

Algae was my problem.

I am adding that about once a month now. I am algae paranoid now.

I just bought some algecide. cost an arm and a darned leg, little 4 ounce bottle was nearly $40 but it treats 500 gallon.
I know my truck has goop in the tank, and the farm fuel tank probably does as well

My hay bailing man showed me there is a sump plug and petcock on the bottom of the tank you can reach if you stick your hand up thru the frame. I tried gently turning on it but it didn't budge. Im going to finish up some things I need to and then get it in the barn so if I break some thing its easy to work on and won't put me in a bind. Hopefully I can wash the tank out thru there and get new parts on it so it can be drained regularly.

Between now and when you get it back to the barn, spray the petcock every time you think about it with penetrating oil. May not help but definitely won’t hurt.

I spoke with my fuel supplier, and he assured me that they use the good additives (apparently they have several to chose from) and I do not need to add lube or algecide. What do you think?
