Does anyone know how too find the current boiling point of gasoline from any supplier?
The following was obtained
HERE. It is relatively dated, but will give some indication.
4.10.1 Vapour Pressure and Distillation Classes.
6 different classes according to location and/or season.
As gasoline is distilled, the temperatures at which various fractions are evaporated are calculated.
Specifications define the temperatures at which
various percentages of the fuel are evaporated. Distillation limits include maximum temperatures that 10% is evaporated (50-70C), 50% is
evaporated (110-121C), 90% is evaporated (185-190C), and the
final boiling point (225C). A minimum temperature for 50% evaporated (77C), and a maximum
amount of Residue (2%) after distillation. Vapour pressure limits for
each class ( 54, 62, 69, 79, 93, 103 kPa ) are also specified. Note that the
EPA has issued a waiver that does not require gasoline with 9-10% ethanol to
meet the required specifications between 1st May - 15 September.

Bold face is mine)
You will notice the figure 225 degrees C (about 425 deg. F) given as the boiling point- other sites place a wide range of 100-400 deg F. The exact boiling point will change w/altitude and the time of year- gasoline is formulated w/different properties depending on the temperature and geographical location.
If I were to take a WAG, I'd say that you're gonna be close at 375 degrees F.
