Fuel Fluke

Well I just got back in from running the motor.

OK.... when I first crank the motor with it running it has (without the electric pump on)7.5psi. When the motor started to get warmer the fuel pressure started to drop slowly. It got to 190* and then the bottom feel out. The pressure dropped to 4.5psi and the fuel started to bubble in the clear plastic filter like it was being sucked out of the filter back towards the tank!!!! I didn't run it any further to see if it was going to flood because it was getting the 200* range...???

I was feeling the aluminum lines, rubber gas hose, filter, carb block, carb the whole time this was going on and non of it felt extremely hot.
