I had a cp3 rebuilt almost a year ago and used it for my dual fuelers. The last 2 weeks I have had suspicion of it leaking so I pulled it out of the valley and put it on top and the top one back Into the valley so I could watch it. Just last night I walked past the truck had could smell a faint fuel smell so I check it out and sure enough there was some wet residue under the bracket the cp3 is mounted to. I inspected the exterior of the cp3 and it is bone dry and clean so I removed the mounting bracket and it was wet under there and against the face of the cp3. The screw circled in red had fuel puddled in it, it didn't appear loose but I was able to snug it up a hair more...is that screw a potential leak point or is there no fuel behind it? Now that I snugged it up I'd hate to drop it off and have them tell me nothing is leaking. I also noticed the weep hole is just below the thickness of the bracket, which could be the culprit but I am unable to tell if fuel has Been coming out of there.

What are my odds of it being that screw?
