My '87 used the same actuator (at the engine) for the Bendix cruise control & the foot pedal. There were some check valves involved.
Any ways, when the cruise was on, it used a LOT of air, so much that the compressor was running more than it was off.
When using the foot pedal, I had to keep adding more pedal to get the motor to rev up. Once the motor started to rev, it continued to accelerate until I completely took my foot off the pedal. Quite aggravating to say the least!
The problem was the rear actuator. I replaced it with a WILLIAMS CONTROLS THROTTLE CONTROL CYLINDER that I got off Ebay. I made a custom mounting bracket & used a throttle cable (also from Ebay). I also modified the KING CRUISE throttle bracket to ensure everything works smoothly.
The results are that I now have predictable throttle response & cruise control that isn't an air hog.
I am very happy with the results.
