My altima 05 gas fuel door cover doesnt want to

what kind of fuel is in it ?

you must buy a new filter like the one your looking @, OK ?

Like many late model cars the fuel system in this car doesn't use an in line filter anymore, this has been the case since the early 2000's, so there is no part number. The only filter in the system is the fine mess nylon screen at the intake to the fuel pump inside the gas tank.

Problems with Nissan 2005 Altima include-Crank shaft position sensor with ECU reset, ECU Factory reset from Dealer, Low Fuel pressure requiring fuel pump replacement, Replacement of ignition coils causing misfire during start-Catalytic Converter Recall-Oxygen sensor on exhaust-Leaking Valve cover gasket-Radiator failure due to plastic top & Bottom (Constantly adding water to reservoir?)

Pull the emergency cable in the trunk on that side to open the gas door and then heavily spray WD40 into the pin latch that holds the gas door closed.Work it back and forth by pushing it in and out with finger until moving freely

Yes, the security system shuts power to the starter and fuel pump. You can try disarming by unlocking and locking the doors the power door locks switch (depends on model). Place the key in the ignition and set to ON, ALL doors closed!! Cycle the locks using the power locks button on the driver's door "lock" then "unlock" if this doesnt work, try same method with the ignition OFF. Otherwise your security system is malf.

The fuel filter and regulator are located inside the fuel tank. They do not require any maintance. If the fuel pump fails, it will come as a unit including the fuel pump, regulator and fuel filter. One less service item you have to purchase.

Try having somebody pull on the gas door as you pull the release inside the car. The black clip you dropped may be a spring to push door open when release is pulled. If that does not work you will have to remove the plastic trim pannel inside the wheel well and unbolt gas door from the back side. That may be difficult if you've never done before. Good luck.

I have a 2003 nissan altima and the door has woked fine all night and now the door will not open from the inside. It is just a broken spring?
