PO had an alloy tank made for my Ambo.
Original size n shape and sitting in the original straps.
Not much help for you as that was in the UK, but it will likely outlast the car.

You may want to give RCI Racing a call, in the past they have built me all kinds of odd shaped tanks. The most recent one was for a custom jeep that held 21 gallons, had all kinds of bends in it, and it was only $220 plus shipping.

My local radiator shop plasma cut an 18" X 18" hole in the top of my 68 AMX tank, sandblasted the interior, TIG welded the top piece back on and used RedKote sealer inside after welding/testing. They drilled a 1/4"drain hole in a corner to drain the sealer, then soldered a copper penny over the hole. The welding doesn't show, it allowed complete access to the interior of the tank and it doesn't leak. Also a non-vented tank. This exercise wasnt't cheap, but neither are any of the alternatives and I kept my original tank with the correctly aligned filler neck. I believe my radiator guy's last words to me were, "DON'T BRING ME ANY MORE OF THOSE!"

The trouble at this point is that previous tank sealing has been done and failed. You would not know the compatibility of a new sealer adhering to the old sealer. Then to compound the problem the leaks may have gone under the old sealers and rotted the metal. The new sealer will not get there either.
Time for a new tank, unless you split the tank, clean to bare metal, re-coat and re-seam (costing more then a new tank).

The biggest problem I saw that none have filler

Also the new tanks are not coated.


It sounds like you should have collected a few filler necks by now, and you can always have the new tank coated if you feel that is necessary.

The tank, from what you have stated so far is scrap.
Next question is what have you been putting in the tank and how have you been storing it?
New vehicles are plastic tanks for a purpose - alcohol. It absorbs moisture, separates the petroleum additives faster (weeks, not months) and is in itself corrosive to steel in that it enhances oxidation, separation and electrolysis.
As advised above, time for a new tank. Then treat it well, with good old petrol and additives if storing. My personal favorite is Seafoam but there are others out there.

Coated or uncoated, a new tank will last one heck of a long time, especially if you paint the outside with something like Eastwood gas tank paint and put something between the bottom of the car, the tank and the straps and the tank where things might rub together.

My guess at that point is the tank will last longer than you...

Have a radiator shop remove the filler neck from your old tank and solder it to the new tank.
