ELECTRONIC FUEL INJECTION
7. Remove the two inner bolts that hold the fuel tank to the
frame.
8. Remove the two outer lower bolts that hold the fuel tank to
the frame.
9. Reinstall the fuel cap and carefully pull the fuel tank out the
RH side of the frame.
Fuel Tank Installation
1. Reinstall the fuel pump / tank assembly.
2. Reinstall the four fuel tank mounting bolts that were
removed.
3. Reconnect the electrical harness. Install the fuel line and
vent line and verify they are secure.
4. Reinstall the RH rear fender.
5. Reconnect the negative battery cable. Test the fuel pump
by turning on the key and listening for the pump to activate.
FUEL PRESSURE REGULATOR
Operation Overview
The fuel pressure regulator maintains the required operating
system pressure of 39 psi + 3psi. A rubber-fiber diaphragm
divides the regulator into two separate sections-, the fuel
chamber and the pressure regulating chamber. The pressure
regulating spring presses against the valve holder (part of the
diaphragm), pressing the valve against the valve seat. The
combination of atmospheric pressure and regulating spring
tension equals the desired operating pressure. Any time the fuel
pressure against the bottom of the diaphragm exceeds the
desired (top) pressure, the valve opens, relieving the excess
pressure, returning the excess fuel back to the tank.
Fuel Pressure Regulator Test
Refer to the “FUEL PUMP TEST” procedure.
See “Fuel Pump Test” on page 4.12.
Fuel Pressure Regulator Replacement
The regulator is a sealed, non-serviceable assembly. If it is
faulty, the pump assembly must be replaced. Refer to the Fuel
Pump / Tank Assembly Replacement procedure.
WARNING
Wear safety goggles while performing this
procedure, failure to do so could result
in serious injuries.
