2005 L39 with over 3k hours. New to tractors but I do know brown sludge shouldn’t be in the fuel system. Went to start it yesterday and it would crank but no start, so I unscrewd the fuel filter and found brown sludge inside. What all do I need to check: tank, hoses? I read that it could be biological but how can something grow in fuel? Thoughts?

Sounds as if you could have a fungus growing in your fuel tank. I recommend draining & cleaning fuel tank & any fuel screens, change fuel filter & add some clean fuel & a fuel conditioner that contains a Biocide

Check your fuel source also. if you have a storage tank that could be a culprit. May of just got a bad load of fuel from the gas station also. Usually water will cause fungus to grow.

Brown like rust, or UPS truck?

Sludge like mud, or slimy?

How long has it been sitting?

Little microbes can live in the thin line between the water on the bottom and the fuel above it, they actually eat the diesel!

If the fuel tank is steel I would suspect rust, if it is plastic then suspect is a biological growth.

Drain the tank, clean it and use the correct preventative methods for whichever problem you have.

You can probably filter the old fuel and use it but I would use it for starting the burn pile myself.

............. but how can something grow in fuel?
I don't understand the "how" part, but I know it's true.

On a side note though, lice do not like it.

Long time ago, in the Marines, a guys kids got lice...He bought all kinds of expensive soaps and crap, nothing worked.........Gunny "T" piped up "Just wash their f''n hair with diesel, shit will be gone in a day or so.......he did, and it was so......Lice gone.

Long story short, 30 years later my kids got lice from school....... and yep you guessed it.

I washed their hair with diesel, and BAM, no more lice.

Our friends called me everything but white, lectured me on "safety' and gave me a world of shit, and "I can't believe it" BS.............TILL she picked it up from her kids.............After about a grand spent on soaps and lotions, and voodoo, magic combs....

.30 cents worth of diesel solved all their problems ($9.00 in todays prices ;))

Oh what fun it was to wash her hair with diesel from my truck........Priceless I say 🤩 🤩

She isn't alive to ask but I think my mom used kerosene!
Some dandruff shampoos have coal tar on their label.

When I was a kid it was common practice to soak feet in kerosene after stepping on rusty nails. Many kids were barefoot during warm weather, even in elementary school. Diesel would taste better than medicine we had to take for colds,caughs,sore throat and stomach elements.
