The stress that is placed on the fuel sender has been reduced by removing the O-ring between the fuel sender and the mounting flange. The reduced stress eliminates the moisture that may enter resulting from cracks in the fuel sender. This change can be identified in two methods. Refer to Illustration 1 and Illustration 2.
