so in a TBI the fuel and air is mixed before it goes into the cylinder like a carb...right?
its not my truck lol. but back to the original question. how is the fuel shot into the cylinder. they cant be shot into the intake valve

just sprays into the intake manifold and get ditributed into each cylinder, not always the same amout tho.

In the pictures you posted it is shot into the intake runner in the intake manifold.
