Installation
The fuel supply module is installed in the reverse order.
Note: When installing the fuel delivery module, be careful not to bend the fuel level sensor float arm.
Note: Insert the fuel delivery module/flange sealing ring dry into the fuel tank opening.
Note: Wet the O-ring with fuel only when installing the fuel delivery module/flange.
Do not bend fuel lines when laying.
Do not interchange the fuel supply and return lines (the return fuel line is blue or marked in blue, the supply fuel line is black).
Make sure the fuel hoses are tightly fitted.
When connecting the fuel line couplings, they should lock into place with a clearly audible click.
After installing the fuel delivery module, check to see if the fuel lines are clamped to the fuel tank.
Observe the mounting position of the fuel supply module flange.
