Posted by Kerry on July 15, 2008, 6:31 am Please log in for more thread options Ok, at 4$ + per gallon I can't ignore this any more. I have a gas tank that leaks when I turn to the right and it is more than half full. The filler tube is my suspect since it is on that side. When I tackle this job I would only be too happy to find that the overflow tube or filler tube has a crack in it after 26 years of service. However I have to drop the tank out to inspect it and when I do I want to be ready for anything....short of buying a new tank in advance. My main concern is that the upper surface of the tank is hidden from view/inspection unless you remove it from the car. So once I have effected a repair on the leak I do not want take it apart again in the near future. If I find some surface rust how should I procede? I know enough to fill the tank with water and leave it. But then what do you folks suggest as a way to seal it up. I could sand off the surface rust and use fiberglass as an outer skin if really pretty pitted. A good priming with Rustoleum rusty metal primer is a thought if the rust is not so deep. I could follow that by a spray of some rustproofing type tar. Unlikely because of how the leak presents itself but if I should find a hole or seam the is leaking what sort of "epoxy" do you find works best. Yes I do weld but I am a self taught stick only kind of guy. I'll repair your utility trailer but much under an eigth of an inch thick and I burn nice big holes in it. This plus the obvious explosion hazzards and my blood pressure would skyrocket so high I wouldn't be able to focus my eyes anyhow. For the record the beloved car is a 1983 Mazda RX-7 so replacement parts are pretty tough to find...and expensive. It has a recess in it's upper surface that allows for the spare tire to be stored or I would consider a simple replacement tank.

Can't say whether he's ever sold a fuel tank or not, but it might be worth asking. He has 2 1st generation RX-7 and looking at a third. One he's parting out for the store -- and his own Rex.

It is very likely that its the rubber overflow or return line thats cracked or leaking, or the rubber boot (if one) between the filler neck and the tank body. Ive owned two trucks where both of those finally cracked and started leaking on turns or when filling up to full.

The access is terrible and I doubt I can take off the rubberboot (as you call it) without cutting it off. the overfill/vent tube is smaller and I will start there. If I cut the boot off I might get lucky and find the hole but still likely going to have to drop the tank to replace it. Here is a thought to further pinpoint where it is leaking. If I were to remove the vent tube and simply wrap the boot with duct tape it should seal any leaks until the glue on the tape lets go. Perhaps a plastic baggy wrapped around the hose then duct tape to hold that firmly in place and a quick trip around the block. No leaks would mean in the sealed section of the hose...well wouldn't it???

The additives in gasoline will eat the plastic just like it will the rubber filler hose. I've got to replace both hoses to a gasoline tank on my FW RV: the $%^& gasohol additives ate them both up.
