It's tough to kill it with air once its running. The IP is very efficient at removng it. That usually means the leak is on the supply side.

I'd check the pre-filter o-ring, shutoff valve and the o-ring at the main filter bolt.

Didnt you just do all your fuel lines recently in an attempt to solve a surging problem?
