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. ________________________________ Message 2 _____________________________________ Time: 12:09:39 AM PST US Subject: Re: TeamGrumman-List: Electric Fuel Pump From: teamgrumman@AOL.COM Do you get any needle movement prior to starting the engine? Look for a minimum of 4 or 5 psi. Odds are, the pump has never been changed. If you have ANY doubt as to it's performance, get a new one. It isn't worth gambling on the mechanical pump alone. -----Original Message----- From: Dwork, Robert Sent: Fri, 1 May 2009 1:27 pm Subject: TeamGrumman-List: Electric Fuel Pump Airplane: 1974 AA5 s/n 0616. I aborted my last flight prior to take-off because I did not see the typical upward movement of the Fuel Pressure needle when turning on the boost pump at run-up. Back at the tie-down, engine off, I did hear the same somewhat sickly growl out of the pump that I've been hearing since purchase over three years ago. Any thoughts on this? Sometimes I question my memory of how things used to be - like yesterday's weather, for example - but now I wonder if I really did see movement of the needle at run-up all these years. Maybe I just heard the pump before start-up and used that as my guide to whether the pump was working, and suddenly I'm looking for something new that was never a concern.

From: teamgrumman@AOL.COM Seems the accessory area temperature was 10 degrees different, hotter, for the new cowling vs the original. Even though the rest of the temps (under the cowling) were within a few degrees. The FAA wants to know why and how it will affect the life of the mags. So, now, I need to get a note from Slick saying 165 degrees vs 155 degrees is acceptable. Never mind that I have 400 hours on my cowling with the ORIGINAL mags that came with my plane still doing fine. ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message teamgrumman-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/TeamGrumman-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/teamgrumman-list Browse Digests http://www.matronics.com/digest/teamgrumman-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
