I'm currently doing a frame off restoration on my Dec 81 FJ40 that I'm converting to a 3B. I have a complete & running 81 BJ42 I'm using for parts since it's body and frame are crap. My question is this, is it true that I have to lift the tub off the frame to remove the fuel tanks? Also, are the gas and diesel fuel tanks the same? The reason is, I'm taking the one in best condition to have it undergo the TankRenu thing. Thanks, SuperDuperCruizer
