Remove the eye bolt while holding the fuel filter nut
\securely.
Caution
Cover the hose connection with rags to prevent splash
of fuel that could be caused by some residual pressurein the fuel pipe line.
INSPECTION

lCheck the hoses and pipes for cracks, bend, deformation
and clogging.
l Check the canister for clogging.
l Check the fuel filter for clogging and damage.

/ 8. FUEL
RETURN HOSE
(1) If the fuel pipe has a stepped part, connect the fuel
hose to the pipe securely, up to the stepped part, as
shown in the illustration.
Iti(2) If the fuel pipe does not have a stepped part, connect
the fuel hose to the pipe securely, so that it is the
standard value.
Standard value: 25
- 30 mm (1.0 - 1.2 in.)
15. INSTALLATION OF HIGH PRESSURE FUEL HOSEApply engine oil to the hose union.
Insert the hose, being careful not to damage the O-ring, and
tighten securely.
CautionBecause there is high pressure applied between the
fuel pump and the injection mixer, be especially sure
that there is no fuel leakage in this area.
12. INSTALLATION OF FUEL FILTER(1) When installing the fuel filter, first temporarily install the
filter to the filter bracket; then insert the main pipe at
the connector part of the high pressure fuel pipe, and
manually screw in the main pipe’s flare nut.
(2) Holding the fuel filter nut, tighten the fuel main pipe’s
flare nut and eye bolt at the specified torque. Then
tighten the filter to the bracket.
