What about adding a new function to your pump, so it would be a bit more useful ?
I think it'd be fun if pump could turn Oil (for example, but some similar things may work for Lava) into a "Raw Oil" and this one could have a slightly different Distillation recipie in your tower ? Like providing 1 Methane Cell for each Diesel Cell (I know, Gasses are like 10% of Oil, but assuming your Methane Cells are Gaseous Methane Cells and not Liquid, because it would otherwhise produce more EU than Refined Oil ... we can assume 1 Methane Cell for each Diesel Cell would be about 10% in terms of mass, or mols if you prefer ^^)
Edit: Why am I still forgetting to edit ? At least that's a good mean to bump the Thread but ...
