6. INSTALLATION
6-1 FUEL SYSTEM
If the fuel tank is detached from the engine, the height from the bottom of the fuel tank to the
fuel joint of the carburetor should be between 5 cm and 50 cm
Any detached tank must have a fuel filter in the fuel feed line with at least 30 micron particle
filtration with a minimum flow rate of 200ml/30 seconds.
The fuel return line must be of at least 3mm inner diameter.
The fuel return line must return to the bottom surface of the fuel tank
An added fuel pump is not needed with the EFI system.
The fuel pump is already integrated into the throttle body assembly
The bottom of the fuel tank can be up to 20 cm below the throttle body
Position the fuel tank carefully because, when it is low, fuel is not fed to the throttle body
When piping the fuel, the hose should be as short as possible and attention should be paid to
heat transmission, size, bending, leakage at hose joints and so on
Care should also be taken to prevent air lock and vapor lock
