It sounds like the gas is safely in your ass, this is good, it's now just a simple matter of transferring the product to the scoot. Please refer to your owner's manual for exact location of your gas tank, then you might first entertain a hose inserted in the "a" hole feeding to hole "b". Gravity will be a factor in this discipline. The physical laws of physics would suggest keeping the "a" hole above hole "b" to avoid backwash. A funnel would also be a very effective systematization, as well as oral delivery.
