From: teamgrumman@aol.com


This one should be easy.

A new owner of an AA1B came in with the vacuum gage reading at the high 
end of the gage.  My first thought was the regulator.  When I crawled 
under the panel (no easy feat in a two-seater) I noticed there was only 
one vacuum line going to the gage and the source was the one port on 
the back of the AI.  I looked on mine and the fitting on the AI from 
the filter (on mine) has a Tee on it going to the vacuum gage and also 
a fitting on the AI going to the vacuum gage.

I looked at a couple of hardware sources and I can't find the 
hose-T-fitting (pipe thread for the AI, 3/8 inch hose fitting to the 
vacuum filter, hose fitting for the vacuum gage) that goes on the back 
of the AI.  It looks like a special fitting.  I called Fletchair to see 
if they had one from an old AI and they didn't.

Any suggestions?
