Oil & Fuel What is this?

[sawtooth]

This is my fuel cap on my 3910. What is the stuff on the cap? Looks like rust? Maybe it is but how would rust form with diesel fuel? The entire tank is lined with it and fuel shut off valve keeps getting clogged up with small particulate. Fuel is orange color too.

Looks like condensation rust.

Can it do that with diesel in tank? Also can I just drain fuel? Or will it continue to be a issue?

Bacteria growing in the diesel.

So a living organism can survive in diesel fuel? Seriously?

Also it's fixed to walls and the cap. You can't scratch it off. But it does resemble rust

It's rust, most likely from condensation, I think Ford had a problem with this on some diesel super duties. You would not think it could happen. But diesel fuel is not engine oil.

Not just survive but actually thrive..

My diesel fuel caps on the JD's are plastic,,, as well as the tank.
Maybe plastic is the right choice,,, for a change?

I never see that,,,

Yep, plastic tank and plastic cap ARE a good thing in this case.

Yes, certain bacteria love oil, as well as the paint, and plastics made from them.

They can eat your siding on your house, the paint off your gutters, your shingles, and the synthetic rubber used to trim your car.

Sell the tractor as quick as you can before it infects something else .

 

[sawtooth]

I think your right. Looks exactly like rust to me.

 

[sawtooth]

I looked up pictures of bacteria on net and don't see anything like that. So next question is if I drain the tank then fill it with fresh fuel will that stop the rust? I know it won't remove it but will it halt the process?

Stop storing fuel (and the tractor) where temp changes cause moisture to be taken into the tank.

The tractor (and the fuel cans, for that matter) can be stopped by keeping the tanks FULL!

My IH has a steel tank, and cap,, I use the tractor, then fill the tank.

Agreed. Actually I had it stored for 3 years now in a insulated barn. BUT the previous owner left it outside. It only has 600 or so hours and was a sun queen for many years before I bought it. I had it repainted as it was so tight and felt like new I just couldn't stand to see it look so rough. Wish now I would have inspected the fuel tank a little closer. Lol

This is my 2810 with just over 400 hours.

And my other 3910 with 668 hours. Runs like a new one but looks like a hag. By way picture was before I corrected the muffle position. Lol
