Definitely a tank with a drain. These old cars sit a lot of time, and after months of sitting, the gas tends to turn to varnish. I have had to drain mine a few times now. You just can't get all the gas out by siphoning it.

Well I got my tank kit from CJ Pony parts, me and my dad are going to install it to make sure the engine runs and to drive it to the next town to get the frame fixed.

Before we do that we wanted to know if we should paint it, or get some sorta protection going on it from rust before we do that?

u can paint it i always use some rattle can undercoating! but the main reason for tank failure is prolonged sitting! and keeping less than a full tank of gas allowing even more of a chance to effect the inside!

Oh I plan on taking this baby out when I can after its almost and all said and done. So leaving it with a full tank will not be a problem, after all the money Im putting into this I plan on taking care of it. I was also wondering, about using the rattle can, when I strip everything off and get it ready for a paint job (sand blasting, priming etc) What should I do with the trunk area to make the tank match with the tank? I plan on getting a trunk mat, but I want it to look prutty.

While you're at it, IF you have a 64.5-68, go ahead and get the 20 Gallon tank for a 1969. I have one in my 66 and it's nice not having to go to the gas station as often (I can go about another 60-70 miles because of the extra capacity) and it drops right in, you'll just have to modify the filler-neck a little.

I would agree on getting a tank with a drain. In the process of draining my old gas and checking the fuel lines I had to drain my tank 2 or 3 times. I ended up putting a petcock type valve in place of the plug. I think it was 1/4 standard pipe thread. It makes draining the tank a lot easier, even though it is not something that you will have to do very often.

Definitely get the drain.

As far as protection, I just used rattle can undercoating on the bottom. On the top, I had the tank and my entire trunk area rhino sprayed sonce it's upholstered just fro protection. The rhino lining cost me about a hundred dollars. Money wel spent IMO.

Rhino lining, huh? OK, well I guess that will work. But, for the inside of the trunk, a good coat of primer and a few coats of color will do the trick. Heck, my tank doesn't have anything on it on the inside, and it is 42 years old with no rust.
