Ernest,
All I know is that it's a pain in the arse when I have to work on the
car's fuel system (no tank drain or shut-off valve).  It brings to mind
a few choice words for the engineers in Detroit.  Seems someone makes a
simple little valve that would be light enough to justify having on
board.  

Or, you could drain the tank(s) if/when the need arises.

The same way everyone does it...that is to say, "I haven't a clue." 8*)

How would you service/replace the valve (short of draining the tank)?

Not trying to be funny there.  Really, how would you.  Would you have to

service a pump any more than you would the valve?  For a minute, I was
thinking that you'd add a small service valve directly under the tank,
but  all that does is move the problem around and increase the
complexity.

Method 1) Would draining the tank be all that difficult?  Fly it down to

5gal (more than VFR min), land, disconnect the fuel line and use the
pump to fill a gas can or two.

Method 2) Have a section of rubber hose before the pump.  Standard
vice-grip clamp cutoff.
