Early in the summer we got my son's '69 with EFI working well. Got great gas mileage on the fwy. However mileage around town was only 17-18 mpg. We puzzled about this for a long time, til one day I was riding with him and he was taking a left hand corner pretty hard, and afterwards I smelled gas. We traced it down and gas was leaking out the rubber to metal boot underneath the fender. The rubber tube that comes out of the trunk is attached to the fill tube with a clamp. The clamp was as tite as it would go and was not actually clamping the tubing. Probly cause the dimensions of the rubber had shrunk over 36 years. I wrapped duct tape around the rubber tube where the clamp went, to make it bigger. Several wraps around and the clamp then functioned properly. No more gas leak on left turns, now, 23-24 mpg in town. This is especially interesting, cause the guy that sold us the car had basically given up, after all kinds of weird fixes (like adding pots in place of temp sensors), because he could not figure out why the mileage was bad. He figured the efi was messed up and running rich. So if your gas mileage seems unexplainably bad, check it out.
