I came into possession of a fzj80 OEM fuel tank at a local junk yard while looking for some other interior parts. Has anyone used a second OEM tank for an auxiliary tank? I know I'd need the plumbing ie dual filler neck/transfer pump/wiring. Was thinking of cleaning up my original tank since I need to redo the filler neck soon anyway (living in Maine in the heart of the rust belt). Tank is ok but filler is in rough shape.
