ok ,today i went wheeling with some friend and on the way back down the trail i landed on my tank and put some good dents in her and i made a tiny tiny crack i think to.where the crack is the gas will not drain out or drip out but a very small amount will seep out after 5 /10 min should i try and fix it or just find a new tank ,any tips on fixing it .im starting a gas tank skid tomorrow lol.now with the rad my has a leak .will any xj rad fit in my 92 xj

I'd replace it. You don't want to weld a gas tank unless you wanna catch it on fire.
