I'm looking to figure out what Vac pump should be utilized for the O-540 B4B5.
Mine died tonight.

It was dark and I haven't yet decowled it.

I looked in the logs and didn't find the proper pump, it just says replaced at overhaul, 871 hours ago. I figure that's pretty good, but cannot find a number in the logs.

Ideas?

What the proper one?
