try tapping on it a bit or banging on it, but before you do, let me tell you that you need a new fuel pump or the hose could have something in it blocking flow or something.

The PGM Main relay is outboard of the glove box. You can see it if you get the glove box out of the way, but to remove it, you need to pop the triangular shaped plastic trim off of the end of the passenger side of your dash. The relay is held in place with one 10mm bolt and the electrical connector.

The relay may be located in the under hood fuse/relay box.
Check your manual for the location of the relay, if listed.
Check for a sticker on the inside of the under hood fuse/relay box for a possible guide.
