Fuel Filter Empty

OK thought I had the problem solved. Everything seems fine idling in the driveway. Since it's below 100 today I took the car for a drive. First thing I noticed is the car idles at almost 1900rpm all by itself after it gets warm. Normal idle is about 700rpm.

Second when I got back to the house I could see large air bubbles in the fuel filter and the filter is no longer full like it is idling in the driveway. Perhaps the new pump is bad. I did not replace it yet. Trying to avoid that but I have ANOTHER new one sitting on the shelf.

Your thoughts, ideas welcome as always.
