Apologies if this has been posted/suggested/reviewed/denied elsewhere but I've looked for two days now and not seen anything about it.
I suggest that the pump have the added functionality of ejecting items directly to a BC pipe. This functionality should take precedence OVER the current ability of the pump to place items directly into adjacent chests. In fact, giving it the same logic that applies to macerators or furnaces when used with a crafting logistics pipe would probably be best.
I can't imagine this being overpowered and I don't think it would be too difficult either but I am in no way a modder so that's just me speculating.
Cheers!
