Dear Arkady, Since you are now in Morocco (?) you may find it easier to obtain hose locally than order from the US.

Fuel pump - canister ( I have no idea what purpose it serves ) * 7x3 high-pressure hose (system works at 3 bar, pressure could rise to 7 bar or more if regulator malfunctions). VW p/n 5m roll N 020 281 1. The canister is a big fuel filter. Some Vanagons have one, some the other, some (like yours) both. Supposedly it's permanent, but I think that's optimistic. p/n 1H0 201 511A. >4. Canister - to fuel line ** 7x3 >5. Fuel line - thru firewall fitting 8x1 plastic tubing, shouldn't need replacing as such. p/n for 5m N 020 130 2. Says also use 2 ea 191 201 316A 6x29 mm sleeve and some N 018 014 1 14x0.8 insulating hose (I think this last may be for inside the engine compartment). The plastic firewall fitting is unsafe -- replace with a metal one or do without. Recent parts drawing shows a grommet and 7x3 hose to pass through firewall. Return line to the tank is also 8x1 plastic tubing but different p/n. 5m roll is N 020 130 2. Also use 2 ea 191 201 316A sleeves. >6. All other fuel system hoses in the engine compartment . The hoses are all shown as N 903 397 02 (fuel hose, 56 cm long) shortened as necessary. Dimensions not stated but I believe list vendors use Conti 6 mm I.D fuel injection hose. The protective sleeving is 15x0.8, 5m p/n N 018 015 4. Good luck, David |
