Looks like the filler pipe is leaking where it goes into the tank on my 33 ford pickup. It’s a steel tank. What seals it? O ring? How do you get the filler tube out? Can it be done without pulling the tank? I maybe can pull the wood up from box to get at it.
You will need a spanner wrench to loosen the outer sleeve. Once it is loose the neck should pull out. Many of the V-8 parts vendors carry the lead ring.
You can try .Order 2 lead seals just in case while you're at it.When I did it in a '35 sedan I had yrs ago I installed a new Drake tank and after assembly it dripped.I cranked on the collar one last time and the leak stopped .Keep in mind as all parts were new.
