    Can't shake vapor lock issue!

    I'll go with that for sure, it just isn't/wasn't getting fuel at idle in gear which the mechanical fuel pump greatly improved what was happening as well as giving it the power it should have had all along and driveability like a late model car. I couldn't make it die at idle running around this...

    Can't shake vapor lock issue!

    Thats what I've come to believe as well. My issues are stemming from the carb being old and more than likely gummed up. I am looking toward upgrading the ignition system or at least replacing the old parts with new ones to add another bit of preventative maintenance. I've had this car for close...

    Can't shake vapor lock issue!

    I ran Seafoam through the carb and then put the other half in the tank and ran the crap out of it after it got up to operating temp. Ran extremely well, ol 318 pulls alot harder with the different fuel pump and having the carb set halfway right. Ran around town after that and had no die at idle...

    Can't shake vapor lock issue!

    I have zero factory parts left of the canister or anything close to it other than the metal line from the tank to under the pass side door. Im going to find a better mouse trap than the crap from the factory. My big block pickup vents only from the gas cap and has never Pinto'd so Im going to...

    Can't shake vapor lock issue!

    I opened the crimped line back up and it still does the same thing. It is indeed venting the tank as it should from that line but still no change. I have another fuel filter to put on tomorrow. If this doesnt cure it, a full fuel system replacement is going to be in order with a mechanical pump...

    Can't shake vapor lock issue!

    Im going to change the fuel filter at my pump as well as get it to do the die at idle and see if I have fuel pressure. I don't see why it could lose pressure only at idle.

    Can't shake vapor lock issue!

    I insulated all my fuel line from under the car up to the carb and still vapor lock action occurs. Even with the fuel cap off it still has the same problem. Im beginning to think my pump is junk, filters are stopped up or something to that effect but that doesnt make sense to me because it...

    Can't shake vapor lock issue!

    Plugs were a light tan but now my water pump, oil pan, trans pan and rear end are all leaking so I'm just walking away from this project for a little while before it ends up in the classifieds! I can't seem to make it idle up much from 700-800 in gear no matter how I adjust the carb or timing.

    Can't shake vapor lock issue!

    I am going to go out on a limb and say the dizzy isn't a smog one. My fuel pump is mounted right at the tank away from the exhaust pipes. I don't have any spacers under my carb but it doesnt get hot, you can put your hand at the base of the intake and it isnt hot even after the engine has been...

    Can't shake vapor lock issue!

    That's a good question, how can I tell it is? I may put one of my Holley's on it and see if it helps any.

    Can't shake vapor lock issue!

    My 74 Dart has a mild 318, factory rad/fan, electric fuel pump and I keep having what seems to be a vapor lock issue. After driving and bringig the car up to 190 degrees it will die in gear at stop signs. It had the Charcoal canister removed and that line was crimped. I have the gas cap drilled...

    running without charcoal cannister

    My Dart didn't have it when I got mine. Previous owner had removed it. Seems to be no issue but if you overfill the car with gas, mine pukes gas out of the line that used to go to the canister. Not a good situation.
