Jet fuel has lower vapor pressure than gasoline.

You are talking about Kerosene aren't you?

“You are talking about Kerosene aren’t you?”

Kerosine, Jet-A, JP-5

I once got the physical properties specification sheet from Shell. Kerosine & Jet-A were identical to three decimal places, in those properties listed for both.

Obviously, Jet-A had additives and a much better clean container/pipeline than Kerosine.
