my bronco is having more troubles. over the summer i posted how my fuel pump shorted out and i had to run a hotwire as a temporary fix. well, the computer has pretty much fried the fuel pump circuit so the hotwire is a permanent fix now.

but NOW the problem is even more troublesome and annoying. here in wisconsin its single digits all day and negative at night. i ran low on fuel one day, let the truck sit for about five days, and when i tried to start it the fuel filter had frozen up because there was a little water in it. no problem, blow it out and the truck started fine.

the next day i had the same problem, even though i filled up the tank and poured two bottles of the red heet in the tank. so i smacked the filter a few times to try to free up the ice, and i got enough fuel to pop and fart. so i disconnected the front line off the filter and smacked it again, hit the key to see i was getting fuel, put it together and it fired no problem at all.
every day since then (a week yesterday) if the truck sits long enough to cool down, it does this.

ive figured out though all i need to do is disconnect and reconnect the front line off the filter and it fires no problem, and its easy enough to do in two minutes from the top, but its annoying.

so why is it that i get no fuel past the filter unless i drain the front line first? could it be some kind of vapor lock that builds up in the fuel rail?
my though is maybe on the return line from the rail, the pressure regulator for some reason closes off the line trying to build pressure back up, so you have to disconnect that line to equalize pressure again. but why would that happen if the regulator is vacuum based?
someone help me out here please.

 

The filter traps water & it stays in the filter. Replace the filter pour a couple of bottles of rubbing alcohol 70% or 90% in the tank. I have used that for years. Also in that kind of weather keep your tank full. Condensation will build up in a tank that is not full condensation is water.
