An excellent idea. But isn't one of the ideas behind using vacuum instruments so they won't have to rely on the electrical system? I could see this as a good thing because vacuum instruments are usually cheaper and surely there is a more reliable pump than on current aircraft but using an electric pump takes away some of the advantages of a vacuum system.
Now that being said we are in an era of many all electric airplanes, EFIS, Electronic Ignition and redundant systems so an electric pump if needed would be acceptable in those craft with redundant systems.

They weight about 12 ounces and barely larger than my fist. At 200 bucks they are a lot cheaper and lighter than an aircraft pump. And I put 280K on my truck before the pump went out last winter. It ran the 4x4, the heater controls and some of the turbo controls. I would think it could run a pair of gauges??

They were used on the Chevy pickups with the 6.2 litter diesel engines. I put well over a 100K miles on one with no problems. They could be belt driven or a coupler could be easily made to drive them direct. Just a thought. _______________________________________ Search the KRnet Archives at http://www.maddyhome.com/krsrch/index.jsp to UNsubscribe from KRnet, send a message to krnet-le...@mylist.net please see other KRnet info at http://www.krnet.org/info.html
