After about 12,000 miles of use the gasket started leaking and pissing fuel from my primary tank. They started to shrink when I got to about 9,900 ft in Tioga pass. I speculate that the elevation and the 20 degree temperature helped the leak along. There must be a better option for drilling into the stock tank though, six holes is a little much. I was worried that this would be a recurring theme and ended up replacing the stock tank. I still have the extended range tank on the bike but I drain it into an MSR fuel bottle and transfer it that way. If I had it to do over again I would just carry a 1 gallon jerry can.
MRAP, if you are interested in selling the tank please put me at the top of the shopping list
