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. Dan Schaefer
