Some engineers are recommending that the discharge line from the Vacuum pump

Yeah, I surely do agree. I ran the output of my pump down and out of
the engine compartment. Seemed the right way to go, though I doubt that
there's that much pressure back there - but what the heck! My friend has
his dump right at the pump and he's got almost 6 - 700 hours on his
Lancair and I think he's still on his first pump. As I said in my post,
we aren't loading them very hard.
Anywaym thanks for the note.
