Working on tanks for a -8 and want to install return lines for EFI system. Does anyone have any thoughts on the location of the return tube? I have heard return it to at least the 2nd or 3rd bay. Are you locating the end of the return line low in the tank so it is always submurged to prevent foaming or just allowing it to "waterfall" when the tanks are low on fuel? I understand you would not want to install the entire return line low in the tank as the pressure of a full tank of fuel would try and flow back through the return line, but I am thinking a sound plan would be to run the return line higher up in the tank near the vent line, then bend the end of the tube downward to the bottom fof the 3rd bay. Ideas or comments? Thanks.
