The first time I dumped ULS fuel into my truck it was about 22 degress outside. I had gelled fuel indications when I restarted up the truck after fueling. I think the fuel was semi-frozen inside the gas stations fuel storage tank as it has been cold here for a while.
My truck still has gelled fuel indications (1 week latter). I haven't had the time to dump the fuel and clean the tank, or blast air into the tank. My fuel pressure starts out at 4 psi and raises to about 6 psi after driving around 15 miles.
Gelled fuel sucks. I have never had a problem with gelled fuel before.
