    Hello boys and girls. I just joined this site looks very helpful I just bought a 78 camaro lt type got it for a great deal. I'm having trouble with fuel delivery I changed the fuel filter at the carb changed the fuel pump. No change, fuel not getting to the fuel pump. I was wondering what to do next . IE drop the tank,check the fuel lines, Please help any info would be helpful.

    Before you drop the tank... Check the rubber connection to the fuel line near the tank, it could be rotted or kinked.

    If that looks good...
    There is a filter (sock) on the inlet to the fuel feed line inside the tank... If there's no fuel getting to the pump (and there's fuel in the tank) it almost has to be that filter.


    Good Luck

    I usually blow in the line to see if I can hear it bubbling in the tank. Then I will hook a mightyvac to it and try to suck some gas out. If a rubber line is bad you should be able to hear the vacuum hissing.

    Thanks for all the help. It was the rubber hoses in the rear near the tank and the ones under the passenger door. All were dry rotted and cracked replaced all and had to crank the engine for a full minute then it turned over. Again thank you for your advice.

    Fwiw

    Personally, I find it's usually the loose nut behind the wheel:)

    Welcome to Nasty stick around, there's refreshments later.

    I find that the nut that holds the steering wheel causes other problems like wrecked cars and such.
