Is the gas cap supposed to allow for vacuum to be pulled into the gas tank, or is the rollover valves supposed to? Seems like (after cleaning tank, fuel strainer) the jeep runs fine, but push it to the floor uphill AFTER driving for a half hour, the truck won't hold 2500+ rpm... left the gas cap loose 1/2 turn for the way home and the issue went away... not low on gas, have 1/2 tank. I'm thinking that the evap/rollover lines are clogged OR the gas cap isn't allowing the air into the tank to relieve vacuum.
it's one or the other i'm sure, just not sure which... it would be easier to put on a new cap than to purge the evap lines...
