Gas tank vent?
Background. Truck is a 1969 250 6cyl 3 speed, original. Original tank.
The paint was gone under the gas filler when I got the truck. Figured it was from people overfilling, but learned the the gas cap was not sealing and gas would run out of tank when making hard right turns. Went to OReillys and got a new cap. It sealed much better, and gas no longer leaks. Now, when ever I take the cap off, there is a major whoosh sound and sometime you here the tank pop, like its getting sucked in. So, I guess the tank is no longer venting. Did they give me the wrong cap? Is there a vent somewhere else that I need to check for?
