   *a	Alignment Opening	*b	Overlapped
   *c	Stretched	*d	Correct
   *e	Incorrect	-	-

   NOTE:

   • Check that there is no foreign matter or damage on the O-ring groove of the No. 2 fuel pipe sub-assembly.
   • Check that the No. 1 back-up ring and No. 2 back-up ring are installed in the correct direction.
   • Make sure that the No. 1 back-up ring, No. 2 back-up ring, No. 3 back-up ring and O-ring are installed in the correct order.
   • Check that the alignment openings of the back-up rings are not overlapped or stretched as shown in the illustration.
   • After installing the O-ring, check that it is not contaminated with foreign matter and is not damaged.
   • Check that the No. 2 fuel pipe sub-assembly installation end is not contaminated with foreign matter and is not damaged.
2. Apply gasoline to the O-ring and connect the No. 2 fuel pipe sub-assembly to the fuel delivery pipe sub-assembly.
   NOTE:

   • Do not install the No. 2 fuel pipe sub-assembly at an angle.
   • Do not install the bolt at this time.

HINT: 

Perform "Inspection After Repair" after replacing the fuel pump assembly.

Refer to INITIALIZATION [04/2013 - 10/2017]

1. Turn the crankshaft pulley until the flat of the cam lobe faces the cylinder head cover fuel pump assembly installation hole as shown in the illustration.

   *1	Fuel Pump Assembly
   *a	Cam Lobe
   *b	Oil Collector
   *c	Correct
   *d	Incorrect

   HINT: 

   When installing the fuel pump assembly by following the procedure described above: By not using the cam lobe nose to push up the pump activation surface, it is easier to install the fuel pump assembly and No. 2 fuel pipe sub-assembly later.

2. Pour 30 cc (1.8 cu in.) of engine oil through the cylinder head cover sub-assembly fuel pump assembly installation hole into the cylinder head cover sub-assembly oil collector.
3. Apply a coat of engine oil to the cam lobe and pump lifter.
