Now that I have replaced the clock spring, I am onto the next issue.

There is an odor of gasoline after running the car. It seems strongest at the passenger side front fender outside the cabin. The quick connect is new at the fuel rail as it was replaced when I did the PCV system maintenance. I have also checked the fuel gauge unit for cracks along the top and replaced the o-ring under the sealing ring. That area was all intact with not odor of fumes nor any cracks evident.

Are there any other known issues of fuel leaking after running the car that I should check?

Thank you,

The fuel line in that vehicle runs up the passenger (RH) side frame rail and along the engine up to the fuel rail. There is a connection under the firewall where the engine assy connects to the chassis frame rail. See if that is wet.

The other thing that I would check is the end of the fuel rail where the pressure sensor is mounted. A very small leak will evaporate on the hot engine but the odor will be pretty strong.

With the engine cold, wrap each connection point with blue paper shop towels. Start the engine and run it for maybe 3-4 minutes. Shut down. Then remove shop towels and see which one is wet. That will give you a clue.

 

 

Just another thought on this. I have had at least 3 xc70's with a leak at the fuel pump itself. On one occasion, the smell of gas was detectable from outside the vehicle more than from inside. Here is a youtube video showing the what I am referring to: (I am not necessarily recommending the fix proposed by this video, I am referring to it because of the clarity of indicating the source of this leak).

What tony1963 said is correct and would be the first things to look at, but with my experience on leaking fuel, it has never been anything but the fuel pump itself.
