The Pulling Upgrade is an upgrade for many machines, similar to the Ejector Upgrade but for inputting items instead of outputting them. It can be used inside any machine which can input items. By default, the Pulling Upgrade will move items from the first valid side it finds. To configure the pulling upgrade, and therefore force it to input only from a particular side, hold it at hand, sneak and right click the side you want the machine to input from. For example, if you sneak right click the top face of a block, the machine you insert the upgrade into will only input from the block above it. This is especially useful when trying to make compact processing setups. Every time the Pulling Upgrade moves an item, it consumes 100 EU.
