Adding fuel return fitting

I'm building the wings on my 650  and the fuel return fitting in on the outboard end of the tank, I talked with Zenith and they said something about that end is better to prevent condensation from getting into the tank from the return line???

Anyway, instead of running a long fuel return line outboard to the next lightening hole I'm considering welding a return fitting in the upper inboard end of my tanks.

Has anyone else done this or is there any reason I shouldn't do this.

Thanks

Tom

Hi Tom!  I'm building a 750, so I'm not familiar with the wing construction you have.  But for what it's worth, I thought I would mention that on the 750, the fuel line on the inboard end of the wing passes through the rear spar. If the return line were to be located at the inboard end of the wings also, it would require that the hole through the spar be enlarged ot tow holes be made, which appears to render the rear spar too weak to carry the wing load at that location. In the 750, all the fuel lines and wiring pass through the trailing edge skin to the fuselage.  Again, this may not apply to the 650 geometry....just food for thought.
