Thank you all for the help here we have a working refinery now - have fuel pumped from the tanks to the engines to keep it powered. There was 68 tanks worth of oil in the ground before it ran out.
Also have a coke oven running on the fir logs, have a chest set up to auto load it, oil goes into another tank-tower and the char-coal gets piped into the base into a chest.
EDIT: i saw a trick about putting a second smaller tower of tanks by it and placing water into one of them so it fills up with the water, incase that happens.
