I rigged up a pump with 4 redstone engines over an oil spout. It pumped almost a tanks worth before the pipe at the bottom stopped extending and stoped pumping oil. I checked and there are no obstructions. I replaced the pump but the bottom pipe stopped extending at the same point. Any suggestions on how i can get it working?
