I had this SAMEEE problem, I caught it at Idle one day. I had to cut off the hose to the regulator, and remove the hard part. That little plastic clamp on the end of the inlet was not creating a seal ( I believe). I got some hose, and 2 clamps and ran it from both ends. It's rand for about a month in the texas heat now and just started leaking again; after tightening the clamps it seems to have fixed the problem but I still see some shitty gas mileage. I no longer smell gas, so believe the problem may be more complex. I'll post my results here
