I'm not sure if I should ask this in the offroad forum, but I figured offroad Fab. Anyways, anyone put a 42 gallon suburban fuel tank in a 2 door yukon or tahoe? From what I see in the parts they are both behind the rear axle and looks the same shape as the 30 gallon just bigger and has bigger straps. The filler pipe is also the same part number between the two. Anyone know the answer to this cause I would really like to empty my wallet filling my tank.
