here's a pic (from behind the rear driver's side wheel):

So, today my car (94 Camry, 2.2l) was parked uphill and with full tank and there was a small patch of fuel on the ground running down from behind the driver's side rear wheel.
First time that I've visibly seen this leak, but I have been thinking that i could smell it on some occations... when i open a window and I'm driving, i guess it produces a back draft from the trunk area somehow making me experience a sligth smell.
The trunk doesn't smell when you open it, but there is like I said some kind of air passage bringing fuel smell in if a window is open.
So, in the picture, I don't know if both of those lines are fuel lines (?). What I can make out is that it's either a leak further up on the thinner line and fuel comming down along the line, causing the wetness of both lines when it gets blown of. Or the leak could be on the thicker line, getting sprayed out somehow under preassure causing both lines to get partially soaked like in the pic.
However it's only when being parked uphill like today (and totally full tank), that it will actually leak while beaing parked. It's not leaking now, that it's parked outside on flat ground.
Any input on this would be appreciated!
