Raw gas smell on 1999 Mercury Mountaineer at rear of vehicle

Now knowing that your not suppose to "top off" your gas tank, I fear I have ruined a major component of the emission system. Since I smell raw gas all time... constant. There are two components on the back by the frame that has one gas line and one rubber hose going to it. What are they, and can they go bad???
Please advise.

Sometimes overfilling will mess up the evaporation canister which absorbs gas fumes. I would have it checked.

Need to replace far back speaker in 99 mountaineer. How does the cover come off

The cover is separate, but I don't remember if it's plastic welded on from the factory. I would recommend removing all of the screws, removing the panels between sides in the rear door jamb area and pull the entire panel back to get to the speaker. There's actually a few good write-ups on speaker removal/installation on the web. The Mountaineer is the same as the Explorer, just under Mercury's name, so don't forget to also look under Explorer if you're looking for vehicle tips. When reassembling the panel, to get the screws to line up with the holes, my trick is to use a long pointed pick or electrical test light, poke through the panel into the screw hole. Once I get the hole, hold the panel, remove the pick and install the screw. I've done this work for 30 years.

I have a raw gas smell comming from fuel tank area

There is a vent on some fuel tanks. As gas gets heated, either from the afternoon heat or from driving, it expands. If your tank is full or close to it, the vapors can escape through the filler tube or some have another vent tube near the filler tube

Mercury mountaineer fuel gauge

According to most mechanics, your problem should be the fuel sender inside the fuel tank.
It might require removing the fuel tank, or, if you are blessed, there might be an access cover inside the rear of the vehicle to get to the top of the fuel tank without removing the tank from the bottom of the car..
Some shops will be recommending replacement of the fuel pump as well, because of the cost and difficulty of doing a gas tank removal twice.
Before going to a lot of trouble, be sure to have someone smart with an electric meter check the fuses, circuit breakers, and such.
God bless your efforts.

I have a 99 mercury mountaineer and it ran out of gas after I put gas in it its like the truck just won't kick thegears ovr do u think I need a new fuel filter or a whole fuel tank

Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they just stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?

You dont need another fuel tank. Running a vehicle out of gas allows any trash or goo to get in the fuel system. Trash mostly is trapped at the pump inlet screen and in the filter. GOO can make its way into the injectors. Throw in a bottle of injector cleaner. A sure indication of a bad fuel pump is an audible constant change in rpm's. It sounds like it's changing gears.

Keyless keypad code

Inside the vehicle behind the left rear quarter interior panel there is a theft module that has a sticker on it with your keypad code.I believe its about 5 numbers.If you have a side compartment on your interior panel you can remove and look above the wheelwell area for the theft module.(gray box.)
