I’m trying to diagnose an issue where engine really stutters on acceleration. It is idling okay but doesn’t want to rev. My fuel pressure on both control and primary is low but adding shims is not helping. I replaced my fuel pump with the new style thinking maybe the old pump just wasn’t putting out enough pressure.

I’m checking a few other things and am wondering if my WUR has a dirty screen or is this the screen itself. It doesn’t look like other pictures I’ve seen.
