You might want to look into an additive for jelling preventative. Some guys mix with Kero, some guys use an additive
HERE Is what I use. I have my wonders on Gelling (possible not too likely), but as it is a possibility, it is also an easy quick cheap fix.
Gel point is the temperature at which diesel or biodiesel fuel freezes solid and can no longer flow by gravity or be pumped through fuel lines. This phenomenon happens when a fuel reaches a low enough temperature whereby enough wax crystals have formed to prevent any movement in the oil. For #2 diesel this is usually around 17.5 °F (−8.1 °C).
