Has anyone had experience with a wet vacuum pump manufactured by M-20 - Bill Sandman’s company? Getting tired of replacing my dry pumps and M-20 “guarantees” his wet pump for the life of the aircraft!!!
Maybe you should ask this guy about vacuum pumps. 
Ew!!!
Well, that’s ONE way to ease tension during your commute…
Now - the question remains… was it wet pump, or a dry one?
Im gonna go with wet. (thats why he passed out) 
“The man was taken to hospital with head injuries”
:?
Uhh… Sucks for that guy (no pun intended).
I was thinking the same thing. (how do you bandage that part of the body?)
rcreighton1, Welcome to the forums. We’re sorry for hijaking the thread so quickly without offering any help.
I have no experience with wet pumps, but I’ve been interested in electric attitude indicators and heading indicators as a replacement. If removes the worry of having a vac pump fail at the worst time. I think they are certified already, I know you can use them as a backup for sure.
User CanadaMooney might have some insight on this issue…
Question:
If he did this in an airplane, would he be eligible for the Mile-High club?
No.
Wet Vacuum pumps have been around for years!
I recently rebuilt a 1959 wood wing mooney M-20 that had a factory install GARWIN wet pump that was good as new!
they last a long time because of the oil bath of the rotor
I guess whether or not he heeded his mother’s advice about wearing clean underwear in case he was in an accident is a moot point… 
It’s dead, Needle. You killed it. It’s done.
Sometimes beating a dead horse is fun!
