Fuel pressure regulators, was Re: Fuel pump questions

ref Ed:
  Personnaly I wouldn't do it that way, the only way for fuel vapors
to purge the line is thru the injectors.  IE, on a hot soak the
light aromatics (higher octane components) star to boil at very 
low temps. (at standard pressure, I beleive some are 130d [summer
blend fue]).  As you approach max duty cycle any air/vapor will
purge, and vapor ain't as dense as liqiud (I bet someone will disagree).
Jus my opinion,
