I installed a Neduro tank on my '03 ADV with the "T" connecting at the crossover hose between the two main tanks under the bike. The bike will use up all the fuel in the main tanks before the fuel in the aux tank will start to go to the carbs. This means that when the fuel light goes on, I basically have about 3 gallons of fuel left which is "kind-of" pointless. But more importantly, taking into account that all three tanks are connected between each other, but the aux tank does not empty it's fuel until the other two are totally empty (as opposed to using the fuel at the same time in all three tanks), I'm thinking I did something wrong by connecting at the lower crossover hose... It works, but... I'd like to hear your experience if you connected the "T" at the hose that comes out of the petcock in the left-main-tank... Is the fuel in the aux tank used at the same rate than in the main tanks ? Or the bike will always use the main-tank-fuel first and then use the aux-tank-fuel? I did read Lobby's awesome thread on the Neduro Tank installation and decided against placing the "T" where he put it (right at the left-main-tank's petcock) because it seemed to me like there was very little room on my '03... Lobby's bike is a 990 and there might be a little bit more room (???)... Maybe my big fat hands just couldn't manage (I did splice the hose, put the "T" right there and it seemed too cramped, so I just replaced the hose and put the "T" under the skid plate) Thanks for your comments BTW having the extra fuel just rocks!!!
