You can either make Lava Cells or Lava Buckets and put them into the Ender Chest. Pipe the excess lava into Tanks and then use a Deployer to fill buckets, a Filter to take full buckets out of the Deployer to the Ender Chest, another Filter to take the empty Buckets out of the Ender Chest into the Deployer. Use the same setup in the Overworld to fill a Geo and Tanks.
