Fuel return line - empty into bottom of tank?

[Bob K]

I am installing a new fuel tank, and I noticed a mfr's tag hanging from the engine (m35) which recommended the fuel return lne empty into the bottom of the fuel tank (using a pickup tube), otherwise, air can enter the system.   My original tank did not have this.  Is this necessary?

No

Bob : I agree with Stu that you don't need a pick up tube for the fuel return line.  As far as air entering the system - makes no since as it's entering a VENTED tank ?!?

Thank you Stu and Ron.  I had never heard of this, but there it was, written plain as day on a tag hanging from the engine.  I'll try to remember to write down exactly what it says.  Tank is installed, but not quite finished.
