It is behaving like an Air Leak to me.
I had a more mild but similar situation. It turned our my Fuel Inlet Hoses were hard an inelastic. Even though the Clamps were tight the Hoses were not sealing on the Plastic Filter. The little bit of roughness I got from that only showed up after everything under the hood was hot.
(Hand Primer?)
When it is running rough like that try pumping fast on the Hand Primer and see if it goes away while you pump.
