INSTALLATION PROCEDURE
KEEP ALL PARTS CLEAN FROM CONTAMINANTS. CONTAMI-
NANTS MAY CAUSE RAPID WEAR AND SHORTENED COMPONENT
LIFE.
DO NOT LET THE TOPS OF FUEL INJECTORS TURN WHEN THE
FUEL LINE NUTS ARE LOOSENED OR TIGHTENED. THE FUEL
INJECTORS WILL BE DAMAGED IF THE TOP OF THE INJECTOR
TURNS IN THE BODY. THE ENGINE WILL BE DAMAGED IF A
DEFECTIVE FUEL INJECTOR IS USED BECAUSE THE SHAPE OF
FUEL (SPRAY PATTERN) THAT COMES OUT OF THE NOZZLE
WILL NOT BE CORRECT.
NOTE: The installation procedure is similar for the two cylin-
der, the three cylinder and the four cylinder engines.
