Fuel smell I have a prevalent gas smell outside the car when I fill the gas tank. The smell subsides as the tank empties. Mechanic has drop gas tank and replaced the fuel pump seal and assembly in December. Car has 122K. No visible signs of gas leakage.

The level sensor is inside the gas tank. A mechanic will need to drop the tank to work on it. Some cars can be done from above. In the meantime, find out how many mpg your car does and multiply it with the tank size. Fill your gas tank, reset your odometer. Keep an eye on the miles you drive and fill up before it reaches the max mileage.

you will have to drop the tank to gain access to the tank unit seal to change. while there check other seals like the vent sensor.

Did you replace the seal on the fuel pump?

Check the fuel hose and clamps from the filler to the tank .check hose for cracks . The smell will probably be strongest in the boot.

Was fuel smell present before you had fuel pump replaced? If yes I would sugest you drop tank and see if fuel vent hose is plugged forcing fuel back pressure line to vent through cap. If fuel smell was not present before you replaced fuel pump and seal. I would suggest you drop tank back out and check all fittings and hose conections. also if you still have old sending unit you could check to make sure they are exactly the same. As Sometimes you have to pull relief valve from old sending unit and install it in the new one, as some sending units wont have one in it. and some will have one that is regulated at a different fuel pressure. hope this helps Vic

take it somewhere with a lift. pay them a few bucks to put it up in the air and look for wet spots. touch the wet spots and sniff your finger, eventually one of those wet spots will smell like gasoline, follow the wet spot to its source and there you go. most likely a gas tank thing, filler tube, rusted spot on tank leaking, leak in the fuel line, etc. it is a fuel injected car, high pressure, so if leak is on the engine side of the fuel pump when it goes it will be a mess and a fire hazard. it is nearly 10 years old so you might want to just drop the tank and replace the fuel pump anyway if you are looking at any serious labor.

Probably needs a new fuel sender unit. They cost about $100. The install may be simple if there is a access door in the floor of your vehicle - otherwise you need to drop the gas tank. Expect to pay $400 to $600 to have a mechanic do it.

don't over fill the tank, when it clicks off thats it!! any check engine light? I had fuel smell, and the O-Ring was leaking when I changed the fuel pump. Top of the fuel tank, was leaking only on a full tank, Also evap, pump and hoses do crack and leak but it will show, in a check engine light usually

wow, not normal, ok u can choose, get it to the garage to repair (will cost lesser then you spelling oil to drive to shops) or selling all the stuff of ure car and buy a new one :) good luck nice car btw

there is a recall on some of the fuel lines under the hood, they get old and leak.
