*Before installing a new filter, always apply a few drops of clean engine oil to the male tube end of the filter and the fuel level meter assembly. This will ensure proper reconnection and prevent a possible fuel leak. (During normal operation, the O-rings located in the female connector will swell and may prevent proper reconnection if not lubricated).
