Like most Fairchild PT owners I have been flying around with a venturi tube to run my vacuum run instruments. And it is nowhere near dependable enough to fly with should I need to reliably fly under simulated IFR work under the hood.

My A&P is trying to find a model of dry Vaccum Pump to put on the PT-26.

I know that they originally came with wet pumps, but he is trying to get away from having to use a separator and all the extra plumbing that goes with that.

So are any of you Ranger "Runners" using a dry vacuum pump and can you share any technical details, like make and model numbers.?

Thanks,

SPANNER

The only reasons the airplanes matter is what the veterans did with them... and why.

tell your A&P to get his head out and put a wet pump on. There is a reason mechanics like dry pumps, THEY FAIL, ALOT, easy money for them, the average life of a dry pump is 6-800 hrs if you are lucky, a wet pump, 3000+.

Are you running just a turn and bank? I put electiric T and B's in my Waco and just eliminated the issue.

I'd like to run an Artificial Horizon and a Directional Gyro in both the front and back seats for doing partial panel Instrument work.
I think I already have electric T&Bs... now that you mention it I need to check that.

Currently the plane just has a venturi tube and the AH and the DHI tumble with just the tamest of turns.
