Thread: Vacuum pump oil return line

Hi all I was going to use vacuum line as a oil return line from the alternator vacuum pump to the block but decided not to as was unsure if oil would affect the rubber. I found catch can oil line would this be better does the return line from the vacuum pump to the block carry any pressure.
thank all.

Doesn't carry any significant pressure from my understanding, from what I've seen (and what I've used) is fuel line of the relevant size.
