Trying to help a buddy here in France. Can one of vacuum ports on the left side of the intake be used for the power brake booster? Originally they were for the dist and vacuum wiper motor.Basically is a 3/16 line out of the fitting.To small? Any ideas ? Much appreciated and with pics.Thanks all
I would say too small as all the PB vacuum lines I have seen are 5/16" or bigger. How big is the fitting on the booster you are planning to use? I would match that and re drill the manifold, or use a spacer under the carb with a fitting on it.
Thanks It is 5/16 .I found a spacer on EBAY that has the port for the Columbia.That might work.Not sure what the size is tho.
