OK.  I'm awake now.  My Cozy will have both wings gravity feeding into a sump.  From the sump, fuel will go through parallel fuel pumps/filters to the rail.  Return from the rail will be to the right wing only.  There will be a facet pump with which I can transfer fuel from left wing to right when necessary.
The coffee smells great :o) ... Jim S.

Matter of fact, didn't I decide last spring to design my fuel system to have left pump draw from left wing, right pump from right wing anyway? Yes I did :o)  Having a senior moment here ... Jim S.Hi Gramps, when you wake up from you nap, take a swig of Geritol, and answer a question for me  :-) What happens if one tank runs out of fuel, and you have both pumps on?   Will some air get pushed into the fuel stream?  I thought about hooking mine up the way you have it, but was worried about this (possible) problem.   I'm still not completely satisfied with my fuel system.  It's hooked up just like Tracy's, and maybe I'll like it better if I ever get that automatic fuel transfer timer set up.  Hey Ed, weren't you the one making that at one time? Cheers,Rusty (young whipper snapper to you)
