    Default 91 Burb only stalls at half a tank full

    My Burb runs great. But when I get to half a tank or less it stalls while accelerating only after a slow down. If I come to a stop it is fine but if I roll thru a turn it will stall. Wont do it when the tank is full. I searched and searched but saw nothing similar. Anyone heard of this or any ideas before I start tearing into things?

    Just a guess here:
    Two thoughts have you been having fuel odors around the vehicle? Is the evap system in good shape? Cannister working correctly?
    Is there a possibiliy the fuel pump pickup has come off or has an issue inside the tank?

    Good idea,the only fuel odor is after a fill up. But I think you are on to something, Good starting place. Thanks

    I would change the fuel filter and run some injector cleaner through the truck as a start both are cheap and even if they don't fix the issue they will only help the truck.

    If the filter change doesn't work,possible internal leak at the pump. I have seen the rubber pump insulator(hose)between the pump and the feed tube split and let the fuel run back in the tank instead of going to the engine. When the tank is full this split is covered up with fuel. One more thought,make sure the fuel cap is venting properly to allow fuel to flow.
