The wife owns a Jeep Latitude. Cute machine that goes through snow pretty well. Great gas mileage - in the summer 32+ and winter 25+. In late winter we started having problems , the gas tank wouldn't fill. The dealer was talking about $2,000 (really!) for replacing the gas line, /breather tube and carbon filter. If that didn't work the dealer's mechanics figured it would need a new gas tank. Dollar signs were everywhere! I took it to an ex-student, a mechanic, and we talked. The system wasn't leaking and it would take .2 gallons at a time. It sounded to me like there was condensed water in the breather line that froze. He agreed and replaced the filter and then blew the breather line with air pressure. it fills like it was new. The total cost was less than $130 (including $30 worth of gas the ex-studend put in to see if we were right).
