Yes I have had this problem. The hose clamp to the rubber hose came loose allowing air into the line, the hose itself looked fine except for a crack and deterioration under the clamp but having to drop the tank to access the line I changed the hose also. If you can get to the top of your tank without dropping it see if the hose clamp is tight or if the hose is cracked under the clamp and just a 1/2 in of hose can be cut off to get rid of the cracked portion. I used a motorcycle jack to drop the tank and only had a 1/4 tank or less of gas in it. Good luck.
