9 Install fuel tank in vice versa sequence and proceed as follows:<\/div>\n
a)\u00a0 \u00a0Glue foam rubber strip on fuel tank at level of filler neck crosswise to driving direction.<\/div>\n
Note: <\/strong>Never use felt or similar material, since other\u00adwise corrosion damage may result.<\/div>\n
b)\u00a0 Blow out filter (b) and check for damage. Renew sealing ring (a). Install fuel filter (68) and tighten<\/div>\n
to 35-43 Nm,<\/div>\n
c)\u00a0 \u00a0Be sure to install fuel tank with specified rein\u00adforcing plates and washers. Tighten self-locking fasten\u00ading nuts to 26-34 Nm.<\/div>\n
d)\u00a0 Install vent hose (arrow) between fuel tank and filler neck free of kinks and with a continuous slope toward fuel tank.<\/div>\n
The slipped-on O-ring serves for sealing at passage to interior.<\/div>\n<\/div>\n<\/td>\n
