fuel leak when cold?

[Re037]

so ive been having this weird fuel leak the past week. it only occurs on cold mornings but quickly goes away once the car is warmed up. i see no liquids dripping so i can only assume its a fuel vapor leak. any ideas?

Yes, very common when it's cold. Tightening the fuel line clamps usually cures it. Here's a photo of where the dozen or so clamps reside. The ones at the front where the fuel rails join are the most popular place to leak, and of course a little challenging. If this doesn't fix it, it could also be the upper fuel injector o-rings, Fuel Pressure Reg or the Fuel Damper are leaking, but usually they won't quit leaking when the temp warms up.
