On the Jetfire, they are really hard to find in running condition with the original turbo. Reliability problems forced most people to abandon the turbo and install a 4 bbl carb. My car has a carbureted 394 c.i. engine.
Vacuum system-I found a tear in a rubber elbow on the gizmo mounted on the strut tower that the alda line goes to and 2" section of vacuum line missing on a rubber Y that runs on top of the fuel filter. Sorry, I haven't received my shop manual yet so I cannot accurately identify the components these vacuum lines go to. I noticed when driving the car last that it took more effort than normal to take the car off of cruise control with the brake pedal and the engine was not making full power. I found some plastic tubing at WWW Grainger that looks like a good substitute for the miles of vacuum lines running thru the engine compartment. I think I shuld change them all and the rubber connections. Maybe vacuum leaks are the suorce of other problems I am experiencing.
Thanks for your advice.
