I have the 5 set point fuel probes. This meant first "finding" how much fuel each tank would hold, then taking it back out and adding it back in, in specific amounts while calibrating the fuel probes. It was long and tedious, however even though I doubled the baggage capacity on this bird, I still hold 23 gallons per side for a total of 46 gallons. I gave up 3 gallons a side for the baggage. No Problem! At 190 kits getting 8gph (a guess) I still have a range of 5.75 hrs which equates to well over 1000 miles. :)
