    OK heres the deal my 77 blazer ran fine a week ago i noticed i had a gas leak from the metal line near the header so i replaced it with a rubber hose.I didnt put no gas in or start for about a week or so and we had some really cold weather.Anyways i put gas in the tank today pumped and pumped and pumped and couldnt get any gas in there finally i decided to put gas in the carberator it started idled really really high then came all the way down and died i tried starting it like this a couple of times and it did the same thing over and over also i noticed when i looked down in the carberator there was no gas spitting into the bowls.Now what i was wondering are my lines frozen or something whats going on here i gave up for the day.Any help would be greatly appreciated.
    Thank you

    I think it needs to be ~ -20 Fahrenheit for Gas to freeze (unless of course there is water in it).

    Sounds like a plugged filter or line.

    Good luck.
     
  3. Did you put the fuel filter on in the correct direction?

    I had the same problem, turned out a leak in the tubing, so it was sucking air.
    Follow the lines all the way from engine to tank.
    If not that then it's a clogged pickup or filter.
