72 oil tank removal

Model: 911T, Year:1972, Mileage:125000, Type of use:Street use only
Hi Ed,I have noticed some minor leaking on the tank. Nothing drips on the floor, just around the tank. I can't figure out if it'd the sending unit, the tank itself or one of the lines. I am not a wrencher type but would like to attempt to remove this myself and figure out what the issue is. I have a picture of the tank that I could send you if that helps. A few q's I have:Is there a detailed write up on removal and reinstallation of the tank that I could follow?How do I test the tank for leaks?While it's out what parts do you recommend I replace and are the part #s easily found? If the tank does not leak I would like to clean it up and repaint it before reinstallation. Detailed steps?Thank you in advance.Joe
