Replaced both of the vent lines yesterday....the 3/8" line had a big blister on it, where it connects to the tank & the hose clamp was gone. The 1/4" line had a slit in it, at the lowest point......this explains the gas leak when the tank was full, especially when parked on a hill. I also added more length to the hoses, so the point that where they are open to vent, would be higher than the tank itself......gravity is very un-forgiving.
I'm just glad it wasn't the O-ring on the sending unit.....I really didn't want to drop the tank.
