Power brake booster vacuum line

[RedD250]

Does anybody happen to know what the part number is, or what the correct part name is, for the vacuum line that goes from the vacuum pump to the brake booster? Or can it just be replaced with any old rubber hose that will fit on the connector? I can't find one available anywere on any parts store, all come back with 0 results. Mine is OK, but I figure that since I'm going to be putting on a new booster, I might as well replace the vacuum lines anyway since they're 30 years old. Thanks!

I wouldn't recommend to replace as long as the old line isn't brittle.
The old rubber is so much better in quality then everything you buy today.

I had many fuel and oil lines replaced on my truck because I thought it'sabout time and all of the new stuff turned brittle within just 2 years, horrible quality. But the old factory stuff 20 years old is still great.
I stopped replacing what isn't broken.
