Eddie,Follow these rules:The tank in the fusealge is the main tank.The tank in the wing is and auxialry tank.The fuselage tank must be no closer than 1/2 inch to the firewall.Both tanks must be vented and vented in such a manner is to prevent iceformation on the vent (even in florida).Both tanks must have a sump and sump drain at their lowest point in a parkedattitude.Air must be able to circulate around the tanks somehow and fumes and liquidfuel must be able to escape down and out from the space beneath the tanks.The fuel for engine use will not be drawn from the main tank at the sump butat some point higher than the sump.Test pressure is 3-1/2 psi for the tanks.And what you asked for: "Where two or more tanks are interconnected and itis impossible to feed from each one separately, only one fuel-level gaugeneed be installed." Obviously the gauge is for the main tank only as theaux tank will drain into the main tank.Copper fuel lines must be annealed after they are bent.Ed, I hope this helps.chris-----Original Message-----

ChrisAgain thanks for some great points that arrive as I am connecting fuel linesand such. Which leads to a related question. I have a main tank in thewing 11 gal. and a header tank in the fuse, 4 gal.with no independant fill,feed directly from the main tank. The question I have been pondering is thevent line in the header tank. I have installed a 1/8" line with a petcockbleed to remove air. Should this have been led back up to the highest pointfor venting? I have a fuel guage on the main wing tank but do not intend onusing that reserve header and no guage installed there.Dick N.----- Original Message -----
