CAUTION:
• Before removing the fuel pressure gauge, release the fuel pressure.
• Be careful not to spill fuel.
• Catch the fuel from hoses using a container or cloth.
NOTE:
Check or replace the fuel pump and fuel delivery line if the fuel pressure is out of the standard.
1. Release the fuel pressure. 
2. Disconnect the fuel delivery hose from fuel damper valve, and connect fuel pressure gauge.
3. Install the fuse of fuel pump to the main fuse box.
4. Start the engine.
5. Measure the fuel pressure after warming up the engine.
NOTE:
The fuel pressure gauge registers 10 to 20 kPa (0.1 to 0.2 kgf/cm2, 1 to 3 psi) higher than standard values during high-altitude operations.
Fuel pressure:
Standard
338 — 348 kPa (3.4 — 3.5 kgf/cm2, 49 — 50 psi)
