If you have warranty, let them deal with it. The hard tank is a pain to remove since the fuel tank has to come out first.
Bow leak:
Hard tank itself
Bow bag itself (checked good)
Lines from tank to bag
Thru fitting under port helm locker
G6 pump system - tank/bow pumps are under floor
How long does it take to kick the pump on? Minutes = cracked tank or broken line. Hours = any of the above things
