TECHNICAL INFORMATION
2.9.8 Guards for fuel injection circuit components
High-pressure injection circuit components are particularly
sensitive to impurities.
To prevent impurities, even microscopic ones, from accessing
the fuel input or output unions, you are required to close these
accesses by means of specic caps as soon as the various
tubes are disassembled and disconnected.
Disassembly of any component of the injection circuit must
not occur in dusty environments.
Cap protections must remain closed in their housing (ST_40)
until the moment they are to be used.
Pay special attention when using the caps and avoid any
contamination of dust or dirt of any kind.
Even after using the caps illustrated in this paragraph, all
components of the injection circuit must be placed with care
in environments that are free of any type of impurity.
Fig. 2.12, 2.13 and 2.14 illustrate the caps that must be used
on components of the injection circuit.
Cap protections must be accurately washed after use and
placed back in their housing ST_40.
Important
• It is highly recommended to have this page visible during
disassembly operations of the components of the fuel
injection circuit.
