this stacking pump system uses 3 yellow inputs (no electric) to feed fuel, and then takes out with just 6 yellow inputs into 3 red storage boxes. To empty level 14, youll need 4 stacks of 6 pumps to empty the floor in about 1 hr (plenty of time to start making yellow science and grey drills elsewhere).

when the pumps are dry - just delete the central core of pumps and leave the fuel and storage intact to trickle feed sand, and to hold more diesel on a way longer line. 6 diesel grinders making pure diesel will run this fine - or 4 and saturate with impure diesel. The third inserter will stack the impure and the first 2 seem to pick up the pure fast enough to keep it running on just 4 crushers making pure.
