Fuel leak at vacuum line from aeromotive afpr

[spydaski]

i dont know why, but all of a sudden, the bottom vacuum line on my afpr going back to the tank is just gushing out gas when i start the car. I have changed the lines and tightened down the clamp as tight as I can and its still pouring out. I didnt change anything or adjust anything and it just started doing this. Did a little research, didnt find much pertaining to this.
Any help would be great. Cars been Out of order for too long. Thanks

The fuel line fittings should be connected with an o-ring boss. Check the mating surfaces are clean and the o-ring is not cracked. Even a tiny break in the o-ring will cause a leak.
