I used 1/4" for my transfer lines and they worked fine. I think it took me something like 5 minutes to transfer the whole 5 gallon tank and you could hear when it was empty. On mine I only used one pump and had it after the fuel selector. I didn't have a return line. If I transferred too much fuel too soon before I used enough in the header it would just dump out the header vent line.

Also transferring to main tank but by 1/4? lines?.. then return overflow to one wing cell again via 1/4 ? Considering more volume under pump pressure than gravity flow overflow to wing? I would appreciate any comments on line size.. or am I being to engineered? jw Joe. E.
