Could have had vegetable oil in it. I tried biobor. didn't seem to do much. The filters are new. I just went to home depot and bought some hose and hooked up a small tank from a boat in the trunk. the car seems to run fine now. there still seem to be small air bubbles in some of the lines. Is it normal that it should take a while to evacuate all the air through the secondary filter and all the lines or is it more likey that i have a leak? I've only driven the car a few blocks.
