(thomas sargent) ________________________________ Message 1 _____________________________________ Time: 01:27:08 AM PST US From: "Jim" Subject: Re: RV-List: Lycoming fuel pump Hi Tom The third fitting is meant to be an overflow outlet. Should the pump fail and begin leaking internally the leaking fuel should exit the pump through the required fitting and its attached hose instead of leaking into the crank case. The vent exit hose/tube should be mounted on the bottom of the firewall well outboard of the exhaust outlet area. It should exit the fuel out into the slipstream.

Keep it away from the exhaust p ipes. It should be on your plans. I think it is there to vent fuel overbo ard if the diaphragms in the pump fail.

Bell" Subject: RV-List: RV-4 Engine Fuel Pump Drain The copper line on the fuel pump overflow plug came loose at the solder joint. No blame my fault! But has anyone come up with another idea that works on the RV-4 fuel pump. As you know it is very close to the left foot well. I used AN fittings and AL line to run the line out the bottom of the cowl. Plastic line would have been more flexible.

From: thomas sargent I'll be starting my engine for the first time pretty soon. I was wondering if is necessary to do anything to get the air out of the hoses that carry fuel and oil to the fuel and oil pressure transducers. -- Tom Sargent ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rv-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RV-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/rv-list Browse Digests http://www.matronics.com/digest/rv-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.
