I'll chime in with my .02 personal experience with a 302.

The pickup looked a lot like yours, and the screen had a hole in the middle which presses against the pickup bottom. I cleaned the pickup to re use it, as I had always done, and got a tad rough with it and popped the screen in, exposing the hole.

Well I popped the screen back out, thinking I was fine.

Apparently, once they pop in, they will do it again under regular operating conditions.

I found this out, the same time I found out that I missed a piece of nylon from the cam sprocket. The pump seized, and the dizzy pin sheared.

A lot of guys with ample rebuild budget will automatically replace the pickup, and a lot of people reuse them. But, if the screen gets popped in, It's trash.
