Air pres gauge &

[williamcharrison]

Thanks to Don Spithaler I found replacing the air governor to be a
relatively easy task. The original was a bendix unit with an
adjustable pres. range of 120-160psi and the new one is 105-125psi.
I turned the adjustment fully clockwise after install but the gauge
still reads ~135psi. There is an orange indicator hand and a green
one and only the orange one moves, the green one is stuck at ~145psi.
Do I need to replace the gauge? Also, I still need to know where
the pickup is located for the boost pressure gauge.
