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 specific caps as soon as the various
tubes are disassembled and disconnected.
D
isassembly of any component of the injection circuit must not
occur in dusty environments.
C
ap guards must remain closed in their housing
(ST_40)
until
the moment they are to be used.
P
ay special attention when using the caps and avoid any
contamination of dust or dirt of any kind.
E
ven 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.
F
ig. 2.11 and 2.12
illustrate the caps that must be used on
components of the injection circuit.
C
ap guards must be accurately washed after use and placed
back in their housing
(ST_40).
