The fuel tank.
•
Disconnect the fuel air vent tube. This is the smaller of
the two hoses attached directly to the bottom of the fuel
tank (NOT to the fuel pump base that is bolted into the
bottom of the fuel tank.
•
Disconnect the fuel pump wires. This is a two pin brown
connector that is attached directly to the fuel pump base.
This connector has a latch that must be depressed to
release it. DO NOT PULL ON THE WIRES.
NOTE: - Supporting the rear of the fuel tank with the
bikes axle wrench is the method shown in the Honda
workshop manual. In practise, we found this did not
allow enough room under the fuel tank. We used a
piece of wood about 180mm (7") long instead. We did
this AFTER disconnecting the air vent hose and the
fuel pump wires, as these were NOT long enough to
allow the tank to be held this high.
NOTE: - The following procedure will need to be carried out fairly quickly as fuel will be running out of
the fuel tank. Make sure that you pre-read the next few paragraphs, and have all the tools necessary
to perform the tasks.
WARNING: - There will be raw fuel and fuel vapours released during this operation.
Make sure that there are NO naked flames or sources of sparks present. Make sure
the work area is well ventilated.
CAUTION: - Make sure that the M12 x 25 (1.25mm pitch) bolt supplied in the cruise control kit is
ABSOLUTLEY CLEAN. You will be using this to plug the fuel injection hose, and there MUST be
NO dirt, dust or grease on it. Use some fuel or solvent to clean it BEFORE you begin working. If
there is ANY dirt on the fuel hose banjo fitting or nut on the end of the injector fuel rail, CLEAN it
carefully before going any further. Make sure that the area around the bottom of the fuel pump base
(the bottom of the fuel tank) is also clean.
CAUTION: - If any dirt or grit enters the fuel hose or fuel rail, it is possible that it may block a fuel
injector. The only way to fix this it to have the injectors cleaned or REPLACED. MAKE SURE
THAT EVERYTHING IS ABSOLUTLEY CLEAN.
