Home-made Pitot & Static line checks

I'd like to check for any leaks in my Pitot and Static lines before riveting on my top skin and starting to bond the windscreen. [RV-8]

I'm looking for ways to provide pressure to the pitot system and vacumn to the static port so I can monitor the Altitude and Airspeed readings on my AFS 3500 EFIS.

It's my understanding that if I can get less than a 100 foot drop of altitude from 1,000 feet in one minute I'm good with the static lines and if I get less than 10 knots of airspeed drop I'm good with the Pitot.

What local "home-made" tools have others used to create vacumn around the static port and pressure attached to the tip of the pitot ?

Dave,
A "vacuum brake bleeder" could be used for your vacuum source
something like:

Should also be available locally at auto parts stores.

I'm sure you can rig up some make-shift fittings to adapt... or machined adapter(s) if needed... let me know.

Rich, Someone from Doug's site suggested building this Manometer and using it for both. I might try it out and see. Will let you know if I need anything for it. Thanks for the offer, and HAPPY BIRTHDAY by the way
