Got the 100 gal aux tank, all plumbing and wiring installed...finally. (Got the tank from TailGunner and then had to do some surgery to make it fit.) Put 30gal in the aux tank and tested it out. There is some wiring problem in the controller, it doesn't automatically come on like it is supposed to, but no leaks and the main fuel tank didn't fall back off on the test drive, so I'm feelin' pretty good...don't even have any parts left over!
