It is always wise, when one knows how accurate the totaliser is, to compare fuel loaded to computed expected fuel. I filled up one time and realised that I had taken 7 Liter more than expected. Sure enough I had a small tank outlet leak. -------- Barry Tennant D-EHBT At EDLM - Germany Read this topic online here: http://forums.matronics.com/viewtopic.php?p=480706#480706 ________________________________ Message 2 _____________________________________ Time: 01:32:47 PM PST US From: William Daniell Subject: Europa-List: UMA differential pressure sender with Dynon Skyview Does anybody know whether its possible to use the 0-7PSI differential pressure gauge (measure difference between airbox and fuel pressure for 914) with dynon skyview thanks Will William Daniell LONGPORT +57 310 295 0744 ________________________________ Message 3 _____________________________________ Time: 05:29:29 PM PST US From: Bud Yerly Subject: Re: Europa-List: UMA differential pressure sender with Dynon Skyview Will 0-30 is the norm for the 914, on yours a 0-15 psi is OK as you run lower pr essure.
