I am currently building a 1935 ford truck with a 455 olds engine i have an old gas tank i got out of a 45 hudson i had professionally cleaned and now i need to know what parts need to go in it on the bottom of the tank it looks like it has 2 plugs on the bottom that are stripped so i am drilling those out but, for the top hat do i need filler tube sending unit..,,,, etc i see other tanks with like three or four holes and gadgets on their tank, it is not EFI?
http://www.tanksinc.com/index.cfm/page/ptype=results/category_id=62/mode=cat/cat62.htm These guys sell some stuff you might need, or at least, give you some idea's. I'd say a sending unit, compatible with your gauge (same ohms), a "pick-up" tube, and a vented cap is the route I would go. Good luck!
