Realistically, no. It isn't. You're talking to the wrong end of the horse. Cause <-> Effect. Your fuel temp is an effect, not the cause. It isn't a paradox. Something is causing the results you are seeing. Elevated fuel temperature is the result of a component failure.
180-190°F is not normal. On mine (2001, but it shouldn't be too far off), the highest temp I've seen is around 160°. That was ascending Pacheco Pass (several miles of 6%) with 22K+ on, and an ambient temp of 118°F. It was as hot as it was going to get.
