I have a factory electro-cruise system in my 1966 Pontiac Bonneville. The ¼ inch spring-reinforced vacuum line that connects the electro cruise power unit on the engine with the cruise release brake switch has deteriorated and needs replacing. I assume the vacuum line was reinforced so that it would not collapse under use – seems odd as I don’t think that much vacuum was generated by the electro-cruise system but there must have been a good reason for Pontiac to do this.

I have not been able to find a part number for this specific vacuum line in the 1966 Pontiac Chassis Parts Catalog and will probably replace it with a braided gas line. I would reuse the existing long reinforcing spring in a new vacuum line but the existing spring does not want to leave the old vacuum line and – and while I could cut it out of the old vacuum line - it seems it would be near impossible to insert the spring into a new vacuum line. Hence the reason to use a braided gas line.

Does anyone have any other suggestions?
