In some cases there are two plugs, one of which taps in downstream of the carb fine mesh screen, allowing you to detect low fuel pressure due to a plugged screen. The 1/8" teflon brake lines with braded shield make a nice connection to a transducer on the firewall, likwise for oil pressure. Try to avoid hanging long chains of fittings on the carb or fuel pump, Vibration may snap them off some day, use steel fittings if you can't avoid it. ===== BILL HANNAHAN WFHANNAHAN@YAHOO.COM >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML website: http://www.olsusa.com/Users/Mkaye/maillist.html Builders' Bookstore: http://www.buildersbooks.com/lancair Please send your photos and drawings to marvkaye@olsusa.com. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
