1. IS THIS COMMON?
AND 2. WHAT CAN I DO TO FIX THIS?
ANY SUGGESTIONS WOULD BE GREAT.

1. What is a long period of time?
2. Is your gas tank behind the front/driver's bench seat?
3. What do you mean by "gas runs back to the tank"? Do you mean the gas line goes dry (drains/leaks dry)?
It most likely does not drain into the tank unless it is siphoning back into the tank (panel/suburban). If it is siphoning into the tank, there might be an air leak near the carburetor?
Maybe someone else will have better advice.
Good luck,
Tim | | |

WE THINK ITS A FUEL LINE PROBLEM AND LIKE YOU SAID ITS SYPHONING BACK TO THE TANK. IF I RUN THE TRUCK EVERYDAY IN GOOD WEATHER I DON'T HAVE A PROBLEM. I WAS THINKING OF REPLACING THE FUEL LINE AND SEEING IF THAT WOULD HELP. | | |

If your fuel line is all steel tube from the tank to the carb, you probably don't have a problem there. If the steel tube is spliced to rubber hose, there's a good chance for a leak. If so, get some Permatex Hylomar sealant (gasoline compatible) and seal the connections.

WHEN YOU SAY LEAKING DO YOU MEAN LEAKING SO I CAN SEE A PUDDLE ON THE FLOOR, OR IS IT LEAKING TO SOME WHERE ELSE? I ASK BECAUSE THE ONLY LEAK I HAVE IS A OIL LEAK. | | |
