ReferenceSpecial Instruction, REHS4449, "Procedure to Align the Dial on the Fuel Sender"

Description of Change: A new fuel sender is now used on the machines that are listed above. The plastic material that is used on the fuel sender has been changed in order to eliminate glazing and cracking. The new fuel sender is more durable in order to withstand the varied operating environments.

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.
