Has anyone come up with a way to monitor vacuum on a 1967 4020 Diesel. Later models had a port and indicator light but I am finding no such port on this one.
Short of brazing or welding a port on the pipe between the air cleaner, oil bath, and the manifold the only posibbility I see is the ether input port. Has anyone used that port with success to monitor vacuum?
Ideas Please?
Paul
