• It is extremely dangerous to remove the fuel pressure relief valve from the common rail as it could cause fuel leakage because the common rail is highly pressurized with fuel. Therefore, do not remove the fuel pressure relief valve installed to the common rail.
1. Visually verify that there is no cracking, damage, or rust on the common rail.
Note
• If there is cracking, damage, or rust on the common rail, it could cause fuel leakage.
