1970 E-body gas cap - 03/15/24 08:56 PM
Does a 1970 Challenger(non CA emmisions) use a Pressure/Vacuum, vented, or non vented gas cap. Thank you.

A 49 state car originally had a cap that said Vented Anti Surge. Cars sold new in CA were Pressure Vacuum. As far as I've found it relates to the tank venting design and either cap will work as long as you have the original 70 filler neck.

Sorry if I'm wrong. I need to look at my original TA gas cap again. I will get back next week with the answer

Just checked my TA locking gas cap and on the backside it has Not Vented printed on it.
