Hello to all,

I have owned a M5400S since the Dec 2005 and it has been great. I used to buy my diesel in four plastic 5-gal containers and go to the fuel depot to buy it, then store them in my garage from the elements [garage was not climate controlled].

I changed the fuel filter a couple of times over the yrs, and it had, I guess, the normal gunk and sediments. About 5-6 yrs ago, I went to a 50gallon drum that is stored in my wooden shed with the tractor [really not climate controlled]. I get it refilled whenever it is 20-30% from empty. I cleaned my fuel sediment bowl yesterday and I was lucky I had an extra fuel filter. The metal top and bottom portion of the filter had a lot of rust on it and the bottom was really full of X. It was also really difficult getting the fuel sediment bowl free because there was some corrosion the top of the fuel shut-off valve head [underneath side] and the large ring that that screws on and off...the corrosion was within the threads and where the rubber o-rings seals the screw ring to the upper body of the shut-off valve. I would assume there was some water in there and that is why the fuel filter rusted.

My the hand pump for my 50 gal drum does not have a filter, so should I get one? The drum is not exposed to the sun and the comp said the inside is coated and it should not condensate. I also try to keep my fuel tank, which is plastic, full as possible. Are there any other recommedations you can make to prevent any possibility of water getting into my fuel tank/system? Should I drain my fuel tank
or take another approach?

Finally, I have not had any issues with the tractor stalling or misfiring from clogged fuel injectors, but I just want to make sure everything I can do to remove water is done, before and during I refuel.

Thank you,
Tstex

I would definitely add a fuel filter water separator before adding to my tank. I would also use a good fuel treatment that will help to treat your fuel system in the tractor.

Tractor supply has a fuel filter base and water trap filter for about $30. That is what I ended up using for my drum set up. Moisture in the air will get into the fuel so I add a fuel conditioner that removes water too.

Does anyone know how or have a suggestion on how to get water out of a transfer tank? Bought a used one and it has some residual water from sitting a long time.

There is a principal (if I can call it that) that you should not store diesel for a long period of time. The amount of diesel that you store you need to be able to consume within a reasonable amount of time. How long does it take for you to go through 50 gallons of diesel?

One thing that you can do to help, is not to let your 50 gallon drum get so low. Having all the void space in the drum invites condensation. Keep it topped off.
