Disconnecting fuel return lines
Caution

disconnecting, as the 4 catches -arrow- can fracture.
● After disconnecting, check the 4 catches -arrow- to see
whether they are fractured or have broken off.
● Always replace damaged fuel return lines.
● A damaged fuel return line that becomes loose when en-
gine is running causes damage to injection valve (piezo
injector). The injection valve (piezo injector) must then
be replaced.
