D. OIL FEED AND RETURN LINES• NOTE:Thehoseandhosefittingssuppliedwiththiskitare

matched to provide maximum performance and life expectancy. Interchanging with other types or brands is not recommended and should be avoided. Should additional hose be required, it may beobtainedfromAMSOILbyorderingpartnumberBP350bythefoot.

• DO NOT install oil hoses near hot exhaust parts or near sharp metal components that could cause abrasive wear.

• DO NOT create sharp bends in oil hoses when installing.

• NOTE: Ensure oil from the engine always comes from the side portofthefilteradapterandfeedstheBK309.OilisreturnedfromtheBK309totheenginethroughthethreadadapter.
