So I've had the fass pump on my truck for a while about a year. I installed the fuel line directly to my cp3 pump and left the originals pressure line there and zip tied it to the motor. I've noticed lately more so after I fill up that I get a leak from that line enough to where I smell it while driving and get a little drip drop here and there. Anybody else's do that? I thought about getting the factory filter delete but that wouldn't get rid of the line. Maybe put a bolt with copper washers to seal it up? Thoughts?

 

I have mine the same way. May want to double check fittings. I had a problem getting the one on the pump tight and it would drip. Did you drain you factory filter? I did do that a few months later.

 

For me, it was the factory supply line to my mechanical pump that I left hanging. I had to fold it over and zip tie it on the side of the road when I noticed it was dumping fuel after filling up.
