One point: My 69 only gets a gas smell in the cab when the tank is full, and I do a hard right turn, which causes fuel to slosh out the filler cap. The driver's window has to be open. Maybe you are getting the same thing happening. My 69 has no EEC.

I had a 71 that often had gas stink in the cab, no one could figure out why. That truck did have EEC.
