Typical example
After the engine has stopped, you must wait for 60
seconds in order to allow the fuel pressure to be
purged from the high pressure fuel lines before any
service or repair is performed on the engine fuel
lines. If necessary, perform minor adjustments.
Repair any leaks from the low pressure fuel system
and from the cooling, lubrication or air systems.
Replace any high pressure fuel line that has leaked.
Refer to Disassembly and Assembly Manual, "Fuel
Injection Lines - Install".
1. Ensure that the fuel supply valve (if equipped) is in
the OFF position. Place a suitable container under
the fuel filter in order to catch any fuel that might
spill. Clean up any spilled fuel.
