5. To bleed the fuel system pressure after the engine is
stopped, place the tool’s bleed hose into an
appropriate fuel handling container. Open the valve to
release the pressure and drain residual fuel.
6. Close the valve, then remove the gauge and adapter
fr
om the fuel hose Schrader valve. Replace the
Schrader valve dust cap.
Disconnect Fittings
The fuel hoses feature disconnect fittings that require
special tools to remove.
The fuel line disconnect tool kit, PS-47152, supplies one
5/16
and one 3/8 quick disconnect tool. These tools are
also commercially available at local auto parts stores.
1. To disconnect a fuel hose from the fuel pump, or fuel
rail, inser
t the tapered end of either the 5/16
or 3/8
tool into the female housing.
2. Push the tool into the housing to release the spring
cla
mps. Carefully separate the hose from the
connection.
3. Reconnect the fuel hoses by coating each hose end
with a lig
ht film of two stroke engine oil.
4. Carefully install the male end of the hose into the
ce
nter of the female housing. Firmly push the hoses
together until the male nozzle fully seats behind the
spring tabs and an audible “click” is heard.
5. Grasp both hoses and gently pull to verify positive
eng
agement.
Fuel Rail/Injector Removal/Installation
NOTE: Leave protective caps installed until
instructed to remove. Avoid touching the tip of the
injector.
A fuel injector, regardless of color code, can be accurately
ide
ntified by the OEM part number stamped on plastic
injector housing.
• 600 = OEM PN 1203491
When replacing a faulty fuel inj
ector, always verify the part
number of the injector for the engine application and use
the same color code. If replacing an injector with a different
color code, all of the fuel injectors must be replaced with
the new color so all four injectors are the same color.
After replacing the injectors, the ECU must be re-flashed
so the fuel calibration map ma
tches the new color coded
fuel injectors.
1. Depressurize the fuel rail. See “Fuel Rail Bleeding /
Pressure Testing” on page 4.18.

ALWAYS CHECK THE INJECTOR PART NUMBER TO
VERIFY ENGINE APPLICATION REGARDLESS OF COLOR
CODE.
NEVER RUN THE ENGINE WITH DIFFERENT COLOR-
CODED FUEL INJECTORS. SEVERE ENGINE DAMAGE
WILL OCCUR.
ALWAYS VERIFY THE ECU CALIBRATION FILE MATCHES
THE FUEL INJECTOR COLOR CODE.
