I have always had a question along the lines of the fuel system, too. Is running the wing tanks dry hard on the fuel pump? It just doesn't seem like a good idea to run the pump without anything going thru it. I understand that the fuel doesn't lubricate it or anything, but it still troubles me. -----Original Message----- From: Syd Cohen <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] <[EMAIL PROTECTED]> Cc: [EMAIL PROTECTED] <[EMAIL PROTECTED]> Date: Sunday, January 28, 2001 9:01 PM Subject: Re: [COUPERS] Need Information on the Fuel system plumbing: >----[Please read http://ercoupers.com/disclaimer.htm before following any advice in this forum.]---- > > Jim, look in the Ercoupe Service Bulletins book (available from Skyport and Univair) for the fuel >system diagram.
