Change-Over Valve Housing, Remove and Install
Important: When
working on the fuel system it is essential to pay attention to
cleanliness as even the smallest dirt particles can lead to faults
in engine operation or in the fuel system. Open fuel connections
must be sealed with appropriate plugs from the Opel Parts Catalogue
(catalogue number: 45 06 154 / part number: 9201697). Sealing plugs
are only intended to be used once.
