Shnalla Posted September 22, 2014 Share Posted September 22, 2014 Hi all, My gas tank buildup too much pressure... When I open the cap, let's say after 15minutes of driving, i hear a big whoosh! I removed the charcoal canister a year ago, and left the line open. I noticed this problem when my engine hesitate and was close to die, and did not rev above 3krpm. It happens sometime but does not last very long. Is it possible it's just not venting properly? My cap is a non vented one. Anyone else with this problem find a solution?

footballubet Posted September 22, 2014 Share Posted September 22, 2014 If you took all the emission lines off of it install a 70 gas cap. They are vented. I did that with mine and plugged all the lines at the gas tank. Quote Link to comment Share on other sites More sharing options...

Arvizu9618 Posted November 13, 2014 Share Posted November 13, 2014 If you took all the emission lines off of it install a 70 gas cap. They are vented. I did that with mine and plugged all the lines at the gas tank. I tried that on my 71's tank and the cap of a 70 wouldnt fit, at least without alot of persuasion. I stuck with my 71 cap, put a filter on the "Tank" vent line and "its all good" Shnalla, You might have an obstruction/clog in your vent line Quote Link to comment Share on other sites More sharing options...
