1964 Buick Electra 225 vacuum lines


Recommended Posts

Do you have the factory chassis service manual?

 

Do you have factory air conditioning?

 

If so look in the air conditioning section, in a 1963 chassis manual it starts on page 11-59 and goes to page 11-67

What is your concern regarding the vac lines?

 

Just curious as they were so simple when compared to anything of the 70s and newer.

There are some missing, just wondering where they go to and from

Distributor should be ported vacuum from the carb base.

Brake booster will be a larger hose hooked to either the back of the carburetor of a rear intake manifold runner, directly.

 

Heater control valve will be (probably) the same size as the vac advance hose, but also from a manifold vac source of the same size.  It can also go first to a vacuum can reservoir/check valve before it goes through the firewall.  Once inside, it should go to the contrl valve on the instrument panel's rear area.  THEN from there, the hoses will go to the various vac actuators that run the valves which open and close the several doors in the hvac box.  There should be a vac map in the service manual for these hvac-specific hoses.  Usually, they were a hose material with more silicone in them, possibly with a color stripe on them.

 

In general, the size of the vac tap is the same size as the tap of the end location.  Same size hose at both ends.

 

Hope this might help.
