If the vacuum canister does not have an integral check
valve, then a separate one is needed in the vacuum
line to prevent the vacuum reserve in the VC from
being lost when carburetor suction decreases. The
check valve may be installed at any convenient
location in the vacuum line between the carburetors'
vacuum source(s) and the vacuum canister(s). Identify
the vacuum side of the check valve; the vacuum side
must be mounted towards the carburetors. The
vacuum side may be labeled, but if you can't tell
which side is which, blow through one end of the
valve (
don't suck on the valve with your mouth
because if there is something in the valve, you could
aspirate it). If the flow is blocked, that's the vacuum
side, but if air flows freely, that's the supply side.
Simply press fitting the vacuum hoses onto the fittings may
allow in-leakage of air into the vacuum system, and thus
reduce the vacuum power available to the servo. Use either
vacuum clamps or silicon sealant on all joints. Cable ties
pulled tight may be used as inexpensive vacuum clamps. If
adhesives are used, apply them only to the fittings and not
the hoses, so that the hoses do not become accidentally
sealed shut.
Make sure that there is sufficient slack in the vacuum tubing and that it doesn't interfere with
anything, or rub on any sharp edges. Trim it to length and attach it to one of the hose nipples on
the previously installed vacuum canister. Attach the remainder to the vacuum canister's second
hose nipple. If there is an additional vacuum canister, run this line to it, otherwise, it will be
attached to the port on the servo after that has been installed.
It is critically important that all joints in the vacuum system are tightly secured.
Poor performance of the cruise control system may result from in-leakage of air
into the vacuum system!
