Why assume a ten year replacement, instead of on-condition? Of course on the rotax we need to use real aerospace 666, not the cheaper automotive hose lacking the interior conductive carbon strip. Having said that, I will share a brief cautionary tale. I removed the crappy VDO oil pressure transducer, replacing it with a modern, aerospace rated (read expensive) transducer I mounted on the firewall. I chose Aeroquip666 with appropriate fittings from the block to the transducer. The hose and the fittings were about $100. The hose worked great for years until.....I was charging my main battery and the ground momentarily made contact with the stainless braid of this hose. Unknown to me at the time, the 20 Amp charge current perforated the teflon liner. No obvious sign on the ground... About a mile off the runway, my cockpit filled with smoke from oil spray onto my muffler. Under engine running oil pressure, that pinhole sprayed quite a bit of oil. -------- Ira N224XS Read this topic online here: http://forums.matronics.com/viewtopic.php?p=439591#439591 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rotaxengines-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RotaxEngines-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/rotaxengines-list Browse Digests http://www.matronics.com/digest/rotaxengines-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.
