General Discussion / gas cap
« on: May 18, 2010, 12:28:00 PM »
Hi Everyone
I just finished a frame off resto on my wife's 67RSSS.
After driving the car a few times I noticed the gas tank
is building pressure! The pressure is so great that the tank pops
when the gas cap is removed! I guess the exhaust heat is causing
the pressure to build. I have a new repop gas cap that allows air in but not out.
Is this normal, if so how does the tank vent?
Thanks fo any ideas.
