So I had a miss while driving my car, so I decided to change the fuel filter. When I crawled under to start taking it off I noticed the metal line was twitsed. I cut it behind the twist and put a new piece on along with a new filter. I got everything bolted back up now its leaking out the top of the bolt that screws into the filter. Any ideas what would cause this? Thanks.

the flange could not be seated properly.
