Before servicing any fuel system components, (such as

contaminants prior to disassembly, clean the fittings,
mounting hardware, and the area around the component

are not cleaned, resulting in damage to the fuel system
and engine.
• Clean the engine. Refer to Procedure 000-009 in

• Use electrical contact cleaner, Part Number

lines before removal from the engine. Clean the
connector fittings to remove as much debris as
possible. It is very important that extra care is taken
to keep the fuel connections clean during removal
and installation. Refer to Procedure 204-008 in
Section i. (/qs3/pubsys2/xml/en/procedures/99/99-
