auto shut off dumps gas on the side

Laysons makes a conversion vent kit to help prevent the overflow. It is pricey though. My '76 Swinger isn't really a problem, but I too listen for the gurgling in the tank and shut it off. My '65 Valiant is a different story. Filler is much lower on the bod. I never fill this baby full anymore. Full tank and a right hand turn equates to gas running down the fender. I just live with more frequent "rest stops". Not a bad thing. The cars always draw attention on the fuel stops.
