Al,

I did read your thread on patching and The pictures helped 100%. The auto vacuum hose you are talking about is vacuum line correct? I have been picturing a big vacuum hose similar to used on a home vacuum... it just hit me you are talking vacuum line hose from an engine....

Anyway I did not refill it but have started documenting the loss as it sits now. It is slowing on the loss per hour... So thats a good sign.

What is done if its at the seam of the stairs etc? I imagine a gasket is under there but the whole concept is pretty darn frightening.
