I beg to differ. Without recirc, the fuel is in the engine area a while
soaking up heat. With recirc, cool fuel is always coming in at
relatively high volume, and the warmed fuel is going back to the tank,
and any global heating of the tank by that is effectively removed by
ambient temps surrounding the tank (plus the volume of fuel there is
(relatively speaking) almost an infinite heat sink. Sre - you shut the
engine off, and it's going to heat up, but if it starts out a few
degrees cooler, chances are much better that it will never reach the
vapor stage.
