I was flirting with the idea of swapping out the fuel tank in my 03 KJ for one from an 06 or 07 for the extra fuel capacity (2 gallons more?). My question is this... because of the higher fuel capacity, I assume the dimensions of the tanks are different. Is the fuel pickup/pump different from 03 and newer?

have you seen the prices for OEM tanks? You might change your mind for only 2 gallons more.Besides that everything else should be a straight swap.

That's why I said "flirting". Might find one at a wrecker for less (maybe).
