One thing with AUX tank, don't put a line in cap to it lower than bike, when it heat up and start draining it will empty you tank and all tanks if it connected to rest.
Had 8 gallon with extra tanks, drained 2-3 gallon out before some called me and said FIRE HAZARD.
My new bike i got separate 2 gallon (5 gallon total) with valve and fill it almost all up no issue with overflowing leaving about 0,5 - 1 inch below cap.
