I'm interested in possibly swapping to this tank on my K/5 to replace the FuelCellGuy tank and big nasty external pump. I hate having to keep at least a 1/4 tank in it to keep the pump happy.
I forgot to do this over the weekend. I'll get you measurements tonight. From what I remember my rear cross member is about an 1" or so from getting too close to the rear body mount. I could have probably moved it back another 1/2" if I needed the space up front.

Just by eyeballing, if my truck was slammed like yours I don't think there would be any clearances issues with the rear diff. Tank looks like it sits back far enough. I'll get you some pics and measurements tonight.
