I put one on my CarbonCub in the spring, then off when it was on floats, now back on to head to New Holstein. It probably took me 25 hours total, there was quite a bit of head scratching. I didnt want to plumb into any of the factory supply lines. I have used an aux tank in the baggage before, and I am a lot more comfortable pumping the fuel to the top of the wing root sight guage, then into a t to fill the tank fom the top. The instructions indicate to tee it down by the fuel select valve. I have seen one Carboncub in a river while pumping off his aux tank this way. With it going into the top of the tank, any boo boo or distraction will pump fuel out the cap vent, or not pump any fuel at all. The internal tank pump pumps about .75 gpm. I put a flasher on the panel mounted annunciator light so it flashes while pumping. I am looking for a used JPI FS 459 to track fuel pumped and left in tank
I guess it gives me the best of both worlds, the lighter empty wt of the short tanks, and then the longer range with 34 gallons in the belly.
Seems a lot simpler to have what you want in the wings from the get go
