The pictures I've seen in the parts catalog from Nissan is that the strainer is a rectangular 'sock'. But they could be using a 'generic' picture.

My fuel pump hat broke off as well. It is very possible it has happened to OP as well, however I never had any of the issues OP posted about. I just had a messed up gas gauge but none the less still check it out
