My 66 had the vented cap system,its real funny when guys use a non vented cap on these ,The tank has no vents at all... meaning the cap has to vent both ways,most caps only allow air in, when a good hot day came along ,tank inside of cab,the rubber fuel lines under the hood would swell up like a bloated radiator hose.....
