vacume mod

[Kisner]

The open tube (about 4 inches long going nowhere) is hooked to the small port of the modulator on mine, while the large port is hooked to about a 4-inch rubber tube which hooks to a steel tube running to the top back of the engine. Where the pipe ends next to the engine, I have another 4-inch rubber tube hooked on that end which hooks to the engine. Like I said, I never knew if any of this was hooked up correctly so I left it alone. The car (and transmission) have run great in the 4 years since it was restored so I left well enough alone.
