Engine hoses/tubing

[donald w. ogden]

Hi Netters

Who has a schematic/diagram of the hose/tube routing on top of the engine???
I'm not sure all my hoses are connected properly. Is it different for each
year/engine?? I have a '77 403. I'm especially concerned about the vacuum
advance connection to the distributor; does it come off the intake manifold or
the carb????

Hi

I have a listing on the web page of where you can get the maint. manuals.

The advance normally comes from the TVS ( christmas tree) valve at the
front of the engine.

You can read some discussion about vac advance on my web page
http://www.california.com/~eagle/howell.html
under vacuum, about different views on this subject.

good luck
