This is valve A32 with a curved-up aluminum reserve tube added, for side mount use on KTM.  The cover panel must be removed, or a large hole cut, to allow access to the substitute valve. There is a reserve capacity on this valve, because the reserve tube curves upward. So the “on” inlet is 2 inches higher than the “reserve” inlet. The bottom 2 inches of the gas tank would be reserve.
