Default fuel pressure rise/temps

I noticed when I go out to the garage and turn on the heat, looking at the gauge on my car(not running) the fuel pressure will rise off zero and climb to over 30 #'s
I have an Aeromotive reg, return, and it dead heads over to the fuel rails
the gauge is on the reg-i guess the rise is coming from the fuel expanding in the fuel rails? is this normal on a dead headed system
I pulled the cap off the fuel tank, but it didn't have pressure (in the summer it will push fuel out the vent)
