Diesel problems

We finally made it back to the farm, and I had 5 gallons of summer diesel that I had drained out last fall and replaced with no. 1. I don't plan on using the tractor in the winter but I want it to be ready. I had put some biocide in the summer diesel before leaving. When I was pouring it in the tractor through a funnel with a fine screen, after about 3 gallons the screen plugged, I had the same thing happen a couple of years ago. There appears to be a fine layer of clear slime on the screen, and if I blow through it backwards it clears it. I didn't put the rest of the fuel in the tractor, I will use it for starting bonfires. Do you think this is bacteria growth or gelling? It was 40 degrees when it happened, but it had been -40 during the winter. I thought gelled fuel would be alright once it warmed up. Thanks for reading!
 
You have algae growing in tank. Add additive to tank. You can get additive that keeps tank clear and with jelling also. Or just algae (slime) additive. Several different brands. I keep it in storage tank adding it when getting new fuel about every other fill up. I'm in Texas but add for both in winter.
 
If you just treat the tank buy several fuel filters while you're there you will need them for the junk that will plug them as you empty the tank running it. Or just drain tank out wash out drain dry and then treat will need fewer filters that way. More sure of getting the alge out of the tank too.
 

Agreed. BTDT with a "deal" on old fuel from the local hospital. They were changing out the generator fuel tanks. Bought 600 gal. for the house and tractors. Got good at changing filters over the next few years.
