Installation of the fuel pump
1. It is best to fix the pump vertically, to the frame or the
secure part of a vehicle. Keep the pump as far as possible
from the engine or exhaust system and other heat radia-
ting parts.
2. Using the pump mounting bracket as template, locate and
drill two 6.2-6.5mm (1/4“) diameter holes in frame. Fix the
pump with 6 mm bolts and nuts furnished in kit. CAUTION:
If the pump is fixed sideways or upside down, the out-
let pressure will not reach the pressure indicated on the
pump. The outside diameter of the outlet and inlet pipes
is 6.5 mm. Use a high pressure rubber hose of 6 mm inside
diameter.
Conventional mechanical fuel pump
Treat the conventional mechanical fuel pump in one of the
following ways:
1. Remove the mechanical pump from the engine, and block
the hole with packing and plate.
2. Pull up and lock the lever, so that the diaphragm does not
function. Then block the inlet and outlet pipes with caps.

Caution
Check the electrical system of the vehicle for voltage and po-
larity, and the needle pressure of carburetor. It will be a cause
of fuel overflow, if the outlet pressure of the Pump is stronger
than the needle pressure of carburetor.
Install the pump correctly according to the voltage and po-
larity stamped on the pump. Otherwise, it will not function
properly.
Wiring and tubing
1. Use 2 meter (6.5 feet) wire supplied by you to connect the
pump wire to the ignition-switch side terminal of the fuse
box, or between the ignition-switch and the ignition-coil.
2. Connect the hose to the pipe and use pipe cramp to fix
securely.
3. Ground the pump securely.
Installation check-up
Before operating vehicle, start the engine and check the in-
stallation as follows:
1. For gasoline leakage in lines and fittings.
2. For overflow in carburetor.
3. For improper and loose electrical connections.
Exchange of strainer elements
Checking and changing of the strainer element are not ne-
cessary when the existing strainer is connected as shown in
Drawing =C= ; Fuel Tank —» Strainer —> Fuel Pump — Car-
buretor, provided that the existing strainer operates properly.
When connection is made otherwise, as Fuel Tank —» Fuel
Pump —> Strainer —» Carburetor, check the strainer element
in the Pump at every 5,OOOkm (3,000 miles) and change for
a new one at 10,000km (6,000 miles).
Remove the fuel pump from the vehicle. Screw off the knob
beneath the pump and take out the strainer element. Do the
work with caution, because a spring is fitted in the pump.
