Check Engine Light "AGAIN' V70-XC70 2001

Alright: One more time! I still have a check engine light on continuously for the last 3 months. However, upon driving home from work each night, there's a distinct odor of gasoline outside of the car at the rear. It is noticeable especially after running the car had. What are the possible issues that I may have to confront? Leaky gas tank? Leaky hose to gas tank? Leaky vent hose to gas tank?
I'm frustrated as hell as I have been chasing this problem for some time. The 2 codes that I have detected with my code reader are: P 0442 - Evaporative Emission System Leak Detected (Small Leak)

and P 1171 Manufacturer controlled fuel and air metering (Air filter, Fuel filter, fuel injector)

Needless to say, This is frustrating!

    Hi Skip.
    My V70 has lived with the P0333 for a long time. Quite often it is from a leak in the evaporative fuel system as you suggested. However, The leak frequently happens at a rubber hose fitting (elbow)at the Charcoal filter. Very difficult to access. Search for that subject in the Forum. I need to fix mine too.

      Found the leak. I removed the back seat on the passenger's side. With little difficulty, I removed the round access panel that covers the fuel pump. The area was soaked in gasoline. It seems to be coming out of the top of the pump unit and not a hose which I thought would be the problem. I suspect that this will take care of some of it. However, I am not sure what else I will have to do. Car runs fine, but gas mileage is down (obviously). Have you ever replaced a fuel pump?
      thanks for your response

        Verify that the fuel lines at the top of the pump are not leaking. They are known for cracking in the 2001-2 fuel pumps.

        If the lines are not leaking, then you will need a new pump gasket.

        See if there was a recall on the 1999 as regards to the fuel pump.

        You will need your VIN for the above link.

          Klaus: Thanks for your response. The gasoline appears to come out of the top of the plastic pump housing and the O-Ring gasket meant to seal the pump to the tank appeared in a small puddle of gasoline by the top of the pump housing. No cracks on the hoses connected to the pump appear to be the problem. I reason that pump replacement as well as gasket replacement is necessary. I need to know if the tank is plastic or metal. If metal, the pump is hard to get. If plastic, it appears to be easier to obtain.

            If you call the dealer's Parts dept and ask nicely, they may be able to determine through the VIN if the tank is plastic or metal. Or, you might inspect the tank and make that determination yourself.

            Clean off the liquid gasoline, start the engine, and try to determine where the leak is. The top of the fuel pump has plastic nipples and they can crack at the base. The seal usually only leaks when the tank is completely full, or full enough that when sloshed around, that the gasoline pushes up against the seal.

            The XC has a saddle tank, meaning that there are two fuel pumps and a fuel line from the driver's side pump goes to the passenger side tank. The passenger side pump feeds the engine.

            EDIT:

            The p0442 is EVAP code. You probably have a broken "J" hose at the rear of the car.

              Klaus: I replaced the fuel pump and the fuel leak is now fixed. As far as the check engine light, I still get the P0442 code. Where is the "J" tube located and what is the part number as I cannot find it on the illustration that I have on the VIDA computer software that I purchased? Thanks in advance!

                Found the cracked J tube! Though this will not be an easy task from the standpoint of accessing the Charcoal Canister above the rear suspension, it will be pretty cheap. $25 - $30. I can reset the code myself.
                What a pain in the ass this has been!
