What temperature does gasoline vaporize at when contained in the typical fuel delivery line? Do you have figures for it both at atmospheric pressure, and when pressurized for delivery (35psi or so)?
AFAIK, different components of gasoline vaporize at different temperatures. Look up "distillation curve gasoline" or something similar online and you may find more info.
Also, gasoline formulations vary considerably, from brand to brand, grade to grade, place to place, with the seasons and with cost and availability of various suitable components Regards
