My CJ-5 vs M38a1 dilemma continues (intro thread): drive train is CJ-5, body is M38a1 (mostly). After a few weeks of being too busy to do much on the Jeep I decided I needed to pull the fuel tank and replace it. Luckily I did the pulling before the buying. I've attached an image of the pulled tank. I could attempt a treatment, but there is a ton of sealant already in the tank that is chipping off due to rust underneath. Aside from condition, this tank doesn't match up with any M38a1 tanks I can see for sale. Prev owner drilled a 6-hole pattern around the 5-hole on the tank. The small hole had a long fuel line soldered to the tank (not welded). Going off measurements, it seems a CJ-5 tank should "fit" under seat no problem (may need new floor pan and filler neck housing). Anyone with more experience than me (just about everyone) have advice?
