Howdy Hank:



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.
