Did the ferrule slip over the line?
Where did you mount the vent? I'm noticing a little gas leaking out when filling up lolThrowing this out in case any one else comes across this thread. This is how I ran my in-tank pump lines and had zero issues. I ran a hard line 90% of the way but used a little bit of EFI hose. My hard line in the rear terminated near the back frame rail and then I ran rubber hose over to the pump. Same went for the front, I ran hard line all the way to the frame rail just a past the fire wall with a rubber line going up to the actual Sniper unit.
