Install the fuel line connections.
Notice
If necessary, remove rust or burrs from the fuel pipes with an emery cloth. Use a radial motion with the fuel pipe end in order to prevent
damage to the 0-ring sealing surface. Use a clean shop towel in order to wipe off the male tube ends. Inspect all the connections for dirt and
burrs. Clean or replace the components and assemblies as required.
19.
Clean the quick-connect fittings.
Caution
In order to reduce the risk of fire and personal injury, before connecting fuel pipe fittings, always apply a few drops of clean engine oil to the
male pipe ends. This will ensure proper reconnection and prevent a possible fuel leak. During normal operation, the 0-rings located in the
female connector will swell and may prevent proper reconnection if not lubricated.
