The Insertion Transport Pipe is an intelligent pipe. When it is connected to a block with an inventory, and the block can accept items, the item will be shot into the inventory instantly. It does this to prevent items from popping out when two items try to fill an inventory with only one open slot. If there is no room in an inventory, the pipe will continue the item along the pipe. However, This will not move the items backwards. Therefore you must have 2 pipes connecting to the insertion pipe in order for this to happen. The Insertion Transport Pipe Will not connect to Cobblestone Transport PiCost
