Well, now that I got a lot of issues sorted I went to top the gas tank off I was at about 1/4th of a tank on the fuel gauge, It took about 10 gallons before fuel started spilling out. I quickly stopped and peaked under and all i could see was fuel coming down from every side of the tank, or so it seemed. What am I looking at here? Any pointing in the correct direction would be appreciated. |

Is filler tube to tank gasket bad? Or is the sending unit's gasket compromised allowing fuel to spill from front to tank? Or is one of the vent or return tubes leaking or missing, is fuel line connected to sending unit? Or is there a big rust hole in the top of the tank? |

I'll have to start hunting these down. Probably no way to check the top of the tank without dropping it, right? Or is there access from above in the trunk? |

i don't know what kind of vehicle you have, but i have recently done mine (75 valiant). assuming you have a similar setup, there is a grommet for the filler neck which is readily available, and it is most likely the source of your trouble. there is also an o-ring where the fuel sending unit is mounted to the tank. if you are going to the trouble of dropping your tank, for no more than these two items (which can and do deteriorate) cost, i would go ahead and purchase prior to dropping the tank. you may also want to inspect the lock ring; you probably will not need a new one (they are reusable), but if yours is damaged they are also available, and cheap. while you're at it, inspect the straps for obvious problems before dropping the tank. mine is a california car, so it has an extra hose. i bought a new float for the sending unit, cleaned the sending unit and the tank with electrolisys (using a caustic soda (lye) solution), and later fitted all the contact areas (i.e. the top of the tank, and where the straps touch the tank) with foam rubber insulation. you can also use strips of inner tube rubber to keep the metal-to-metal contact from rubbing a hole in your tank. also be sure to get a good ground with the grounding clip (found on one of your fuel lines) or the fuel gauge will stop working. oh, and as stated above, the less fuel in the tank the better! |

Yeah, using the fuel as I can. Too hot here in CA to drive it too much, but I drove it to work today, used less then 1/4th of a tank. This may take a while. Thanks for all the tips. |
