This thing has been doing great for 20+ years and no problem
Not a instant thing but it will stop it from producing more I would drain it as much as you can then flush it out with clean heating oil or kero if you can find it.I will have to go get me some
We've dealt with this before. Diesel fuel is known to always have a small percentage of water molecules in it. Since the switch to Ultra low sulfur diesel in the mid 2000s, the water molecule content has increased slightly. Not a problem in vehicles usually where it doesn't sit for months, but in storage tanks like our dual 450s, it can foster an environment to allow algae to grow. Especially if the tanks are stored outside. Now, there are products out there designed to kill the algae entirely. Best thing we've found is to drain the fuel tank entirely. Get a few gallons of gasoline and pour into the empty diesel tanks, slosh it around a little bit, by rocking the tank, drain it and leave the filler and drain open for a bit to vent all the fumes. Close the drain,Then pour in one of the treatments, the best is called Liquid Moly Anti-bacteria treatment. It's for diesel fuel algae killing. There's others out there as well. Available at any farm store and some Walmart even. Pour that in, refill the diesel tank with fresh fuel. Replace all filters and the flush the lines out of the old fuel. This normally solves the problemThis thing has been doing great for 20+ years and no problem
No it is an outside tank. It has been working for over 20 years and all at once this year it has been a real problemYa, i had to read back some. Algicide. Its a thing.
Yup, its a big biodiesel problem.
lots of tractor forums speak of it.
The problem started with delivery of tainted fuel. Adding a clean-able screen will lengthen filter replacement intervals,but screen will need to be cleaned.
Indoor tank? Hope not.

Read my above postNo it is an outside tank. It has been working for over 20 years and all at once this year it has been a real problem
But it would be nice to have heat! NowWe've dealt with this before. Diesel fuel is known to always have a small percentage of water molecules in it.

Simple enough to temporarily get a couple gas cans full of diesel fuel and rig a line in while you clean and treat the tank. It doesn't tank but an hour or so.But it would be nice to have heat! Now
Where do you get these? At a tractor store? I tried the Hot shot crap from ACE hardware@dartnabout these are a couple of the ones we've used.

Any farm supply store should have them. Walmart here does as well. But we're a having agriculture area.m so I doubt every Walmart does but I could be wrongWhere do you get these? At a tractor store? I tried the Hot shot crap from ACE hardware
Why wouldn't it? Just get a filter head and filter from a tractor supply store and put in the line. That's what we did.I always wondered if a spin on oil filter would work on them?
