accommodate the fuel pump wires.

Note: Ensure that the hose clamp & fuel pump wires are not rubbing.
Under no circumstance may the combustion air be taken from areas occupied by people. The combustion air intake
opening must not point in the direction of travel. It must be located so that it cannot become clogged with dirt or
road debris.
The combustion air must be extracted using a combustion air tube supplied in the kit and protected from dust and
water ingress.
