Re: [Chrysler300] 'Negative' gas tank pressure

[retromobilia@xxxxxxxxxxx]

Most car as you back in time had all mechanical systems vented to the air; Gastank. Differential, Transmission, Engine, and earlier Radiator and some later positive pressure relief. Some/most tanks were vented at the cap; And if a modern fuel cap is used it may not/ will most likely not be vented and the negative pressure builds up and then you found out what can happen....

My 62 300H has a vent line from the tank to the outside-do the earlier cars not have such a vent?

I believe your conclusion is correct Ron. He should get it vented quickly. I actually had a replacement tank on my E collapse in all 4 corners from this negative pressure after redoing the whole fuel system. Would not have believed this possible unless I had seen it happen. 1/8" hole preferred solution over installing a new tank,
