Thanks, NSEU.
Despite the steep temperature transfer gradient, the large differences between surface areas of the hydraulic lines/exchange devices and the tanks coupled with other factors would militate against the fuel retaining a significant degree of thermal energy. Pretty obvious when you're less silly than me!
