All fuel-carrying components have to be installed with enough distance from any hot component to
prevent danger from fuel ignition or explosion. (ie. exhaust system).
Each fuel line has to have a pipe clamp installed for security. The fuel lines between the fuel filters
and the engine must be made of fuel durable material and resist a pressure of min. 6 bar.
The fuel return line to the fuel tank must have a diameter of 8mm or 0.312 inches to prevent back
pressure.
With a dual fuel tank system you must pay close attention that both fuel tanks are connected to each
other in such a way that uneven fuel levels do not occur from fuel return.
On dual fuel tanks which are controlled separately, you must have an overflow connection installed,
or it must have a fuel return valve that will direct fuel to the tank that is in operation so as not to
deplete operational fuel tank or create an overflow situation.
2.5Fuel injection wiring installation
1.Install the engine according to the installation instruction.
2.Install the computer at a suitable place (pay attention to the length of the wire harness)
3.Install the wire harness according to the above-mentioned connections and connect the blue plug to the
computer.
Note: The blue plug can only be connected in one position with the computer.
4.Connect the power supply (red +) with the on/off switch. The supply line to the switch has to be installed
according to the above mentioned instructions. Connect the power supply ground (black -) to a ground
or even better, directly to the (-) negative pole on the battery.
5.Install the fuel pump (close by the fuel tank), and lay the pressure line from the fuel filter to the engine.
Secure them with the pipe clamps (Figure connection to the engine-connection to the filter).
6.Connect the supply line from the fuel tank to the suction connection of the fuel pump/fuel filter (big pipe
connection) and secure them with the pipe clamps.
7.Secure the relay supplied to a suitable location within close proximity of the fuel pump
8.The green and black wires from the harness are connected to the location points 85 and 86 of the relay.
9.Connect the positive (+) separate line from the switch to the location point 30 of the relay.
10.Connect from the location point 87 of the relay to the positive (+) connection on the fuel pump.
11.Connect from the negative (-) of the fuel pump to a negative (-) point of the battery. Please ensure all
connections are suitable for at least 8 Amp?s
12.Hook the throttle cable to the bell crank of the TBI (Figure 2.5-1 Position 5), page 22. Adjust the throttle
cable with the adjusting screw (Figure 2.5-1 Position 2) so that the throttle cable in the idle position has
some play (2-4mm or 0.078-0.156 inches) and secure with the locknut (Figure 2.5-1 Position 1). Make
sure that the idle stop (Figure 2.5-1 Position 5) nut is adjacent to the throttle stop (Figure 2.5-1 Position
3).
13.Synchronisation of the throttle control
Open the throttle a short way and take care the space between the throttle and the throttle body is the
same width at both throttle bodies. Use a round object for that. Fix the throttle in a position where the
round object has the same diameter than the width of the crack. Check for the same distance on the
opposite throttle body. Adjust accordingly. When the throttle is set to the idle position, both throttle
adjustment screws must contact the throttle stop. Allow only a small amount of play in the throttle cable.
