io-390 fuel return line?

[grubac]

Hey Guys

Just a quick question about the IO-390.

With the Precision Airmotive's RSA system, I've heard that a return fuel line is not needed. What I'm wondering is, how is it possible to then purge the fuel lines? Is a purge valve needed? Is there still a return line between the fuel selector and the tanks?

Any help would be much appreciated
