The first time I put the sending unit back in I had a leak. I had a new gasket, cleaned the mating surface of the sending unit and made sure that the clamping ring was centered, but did not adequately clean the mating surface of the tank. The place where the sealing happens is beneath the lip where the clamping ring goes. It is difficult to get under there to completely clean out the oxidation and deposits. But once I did that it sealed up nicely without any leaks. I used fine emery cloth and then 600 grit sandpaper for the final cleaning.
