What fuel valves are flyers of the 320/360 using with the Header tank config?

Do I need a left/right/header/ off selector valve? 

The set up I have is such that the wings feed into the header tank and the header feeds the engine.

 

Bryan,

 

A useful mind set is to consider that header tank equipped Lancairs have only one fuel tank (the header) and two aux tanks (the wings).  Thus, a one tank airplane only needs a shutoff valve between the tank and the firewall forward components and pumps to move the fuel from the aux tanks to the main (header) tank.

 

Most of us don't have selector valves (and the associated headaches).  There are many clever schemes for managing the fuel level in the header.
