1.  lift and support the fuel tank. Refer to “fuel tank removal and installation” .
2.  Place a rag under the fuel feed hose (1) and remove the fuel feed hose.

3. Install the special tools between the fuel pump and fuel delivery pipe.

Special tool (a): 09940–40211 (fuel pressure
gauge adapter) (b): 09940–40220 (fuel pressure
gauge attachment) (c): 09915–77331 (oil pressure gauge
(1000 kpa)) (d): 09915–74521 (adapter hose)

4. Turn the ignition on and check for fuel pressure.

Fuel pressure approx. 300 Kpa (3.0 Kgf/cm2, 43 psi)

If the fuel pressure is lower than the specification, check for the followings:

•  fuel hose leakage
•  clogged fuel filter
•  pressure regulator
• Fuel pump

If the fuel pressure is higher than the specification, check for the followings:

•  fuel pump
•  pressure regulator
