Changing the Vent Hoses
As posted by Bobbo on 8/27/2002 in a post entitled "Changing those
pesky vacuum lines", it can prove to be a real nuisance when changing
vacuum hoses on our Valks. If you remove the air box, you will see that
3 vent hoses are connected to the intake manifolds. 2 of these, which are
connected to carbs 3 and 4, are fastened via a T Connector (and another
small hose) to the pair valve. You can see the pair valve with the T
connector, etc. in the middle of the picture. The idea is to disconnect
the hoses from carbs 3 and 4, and to tie a string to each of these. You
can see these strings on each side of the picture. Disconnect the hose (in
the middle) from the pair valve and pull everything upwards.
Note: These strings will enable you to pull the new hoses back into the
appropriate places. |

Clone the Vent Hoses
Measure the hoses, cut new hoses of the same length, and connect these
to a T fitting (new or existing one). Untie the strings from the old
hoses, and tie them to the end of the new hoses. Carefully pull the
strings to snake the new hoses back to carbs 3 and 4.
Connect the new hoses to carbs 3 and 4, and to the pair valve.
Note: Carb 6 is easy to do. Use a string in the same fashion as done
above for the pair valve vents. |
