I’m gonna try to set up a fuel pressure gauge at the end of the feed line tonight if it’s not to dark when I get home.
From what I remember Rattle is no good- if you leave it installed and just unplug it then it should make the motor knock like a 12v. Plug it back in it should go away. If removed and it is rattling it should be replaced
