If the pipe clamps / quick fix couplings found
deformed, bent or broken, replace with new one.
Assembly :
1.
Do not tighten the clamps used on breather hose /
filler hose excessively to avoid damage to hoses.
Use suitable tool for fitment of clamp.
2.
Fuel hoses to fuel pipe connections varies for each
type of pipe. Necessary care to be taken to connect
and clamp each hose correctly.
3.
Ensure that quick fix couplings are fittedproperlyon
to pipe,filter,pump fittings.
4.
Donot kinkor twist hose / pipewhen theyare routed.
5.
