Figure 4-59. Fuel Pressure Gauge Installed (Typical)
To prevent spray of fuel, be sure quick-connect fittings
are properly mated. Gasoline is extremely flammable and
highly explosive, which could result in death or serious
injury. (00268a)
5. Verify that the fuel valve and air bleed petcock on the
FUEL PRESSURE GAUGE (Part No. HD-41182) are
closed.
6. See Figure 4-57. Remove protective cap from free end of
fuel pressure gauge adapter. Connect fuel pressure gauge
to Schroeder valve.
7. See Figure 4-56. Install fuel pump fuse.
8. Start and idle engine to pressurize the fuel system. Open
the fuel valve to allow the flow of fuel down the hose of
the pressure gauge.
9. Position the clear air bleed tube in a suitable container
and open and close the air bleed petcock to purge the
gauge and hose of air. Repeat this step several times until
only solid fuel (without bubbles) flows from the air bleed
tube. Close the petcock.
10. Open and close throttle to change engine speed. Note the
reading of the pressure gauge. Fuel pressure should
remain steady at 55-62 psi (380-425 kPa).
NOTE
If fuel pressure gauge reading is not within specifications, see
electrical diagnostic manual for further diagnosis.
11. Turn the engine off. Position the air bleed tube in a suitable
container. Open the air bleed petcock to relieve the fuel
system pressure and purge the pressure gauge of gas-
oline.
Gasoline can drain from the adapter when gauge is
removed. Gasoline is extremely flammable and highly
explosive, which could result in death or serious injury.
Wipe up spilled fuel immediately and dispose of rags in a
suitable manner. (00254a)
12. Remove fuel pressure gauge from the adapter. Install
protective cap over Schroeder valve.
Gasoline can drain from the fuel line and adapter when
removed. Gasoline is extremely flammable and highly
explosive, which could result in death or serious injury.
Wipe up spilled fuel immediately and dispose of rags in a
suitable manner. (00255a)
13. Pull up on sleeve of quick-connect fitting and remove fuel
supply line from fuel pressure gauge adapter. Release
adapter from fuel tank in the same manner.
To prevent spray of fuel, be sure quick-connect fittings
are properly mated. Gasoline is extremely flammable and
highly explosive, which could result in death or serious
injury. (00268a)
14. Pull up on chrome sleeve of quick-connect fitting (forward
fitting on left side of tank) and insert neck of fuel supply
line fitting. While pushing up on bottom of fuel supply line
fitting, pull down on chrome sleeve until it "clicks" into the
locked position. Tug on fuel supply line to be sure that it
will not come free.
15. Install electrical caddy cover.
