EC-48, "FUEL PRESSURE RELEASE"

–

c) Disconnect battery ground cable.

●

Always replace O-ring and clamps with new ones.

●

Do not kink or twist tubes when they are being installed.

●

Do not tighten hose clamps excessively to avoid damaging hoses.
Tighten high-pressure rubber hose clamp so that clamp
end is 3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.

●

After installing tubes, make sure there is no fuel leakage at
connections in the following steps.

–

a) Apply fuel pressure to fuel lines with turning ignition

switch ON (with engine stopped). Then check for fuel
leaks at connections.

–

b) Start the engine and rev it up and check for fuel leaks at

connections.

●

Use only a genuine NISSAN fuel filler cap as a replacement. If an incorrect fuel filler cap is used,
the MIL may come on.
