    Can anyone tell me the vacuum hose routing for a 72 GS 350 from the front intake mounted sensor .
    The sensor has three ports as well as the top electrical connection.

    Appreciate any assistance.

    Paul,
    This picture is from a 72 Chassis manual. Does it look like this.

    or this. There are a few more pictures depending on weather the car was equipped with A/C.

    Thanks for your help Larry. It appears mine is closer to the top picture you supplied.

    Only difference is I have three side ports.

    When I bought the car it had an aftermarket breather now trying to reinstall the original

    My car does have air.


    Appreciate the help.


    Thanks

    If you look close at the vacuum switch it should have letters corresponding to the correct hose connection such as "C" carb and "D" distributor and so on. Most I've seen do.

    I've always wondered, exactly what is that thing with the vacuum ports that threads into the intake? Whats it do?
