If you post on
www.agriculture.com a bunch of farmers will be jumping opn this with both feet, and a load of suggestions.
Gelling is primarily due to water contamination. You may also have microbial contamination witch is an equine of a different hue.
Diesel is a lot like mayonaze, and 2 problems occurr when Diesel is pumped, or moved. Diesel incorporates both air & water, and it takes about 12 hours for both to settle out.
Most problems caused by gelling are alleviated by fueling the machine at the beginning of the day rather than filling at night, and letting the machine sit overnight.
Observe aircraft fueling operations, they fill the truck from the tankfarm, and let the truck sit for hours to let the water and disolved parafin settle. Then they drain 5 gallons from the bottom of the tank, before fueling an aircraft. Aircraft do not sit around after fueling, they takeoff.
Gelling will rarely occurr on a running diesel, because the fuel that doesn't go to the injectors is circulated back to the tank.
Using gasoline and kero or jp as an antigell is a last resort. Different engines will tolerate different levels of dilution, so it would be best to check with the engine manufacturer.
Are you filtering your diesel before it goes into the machine? Filters will remove most of the excess parafin and most of the water if used properly. Also, a lot of problems can be eliminated by raising the pump pickup up in the bulk tank.
