Suzuki GSX-R 1000 Service Manual: Fuel pressure inspection
|
|
Inspect the fuel pressure in the following procedures:
- lift and support the fuel tank. Refer to “fuel tank removal and installation” .
- Place a rag under the fuel feed hose (1) and remove the fuel feed hose.
- 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)
- 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
- Remove the special tools.
 Before
removing the special tools, turn the ignition switch off and release the fuel pressure slowly. |
- Reinstall the fuel tank. Refer to “fuel tank removal and installation” .
| Note connect the fuel feed hose to the fuel pump until it locks securely (a click is heard). |
