Mpg over fueling?

[Bertman]

I've had mine leak from connectors to the lines direct to/from the fuel rail. Couldn't notice with the engine running but if you stopped it running the fuel would slowly seep out at the connection. Plus as mentioned rear elbow.... only leaked if I parked the car backwards on the drive (hill). The top of the pipe was cracked so didn't leak on the flat, but was enough for the fuel to evaporate off. Does the car smell of fuel?
