"99 Miata Gas Smell.
Ron
overfilled and the cap is good. Been this way for a while. Just now
getting around to trying to fix it. Any ideas?

I would check the fuel line and fuel rail/fuel injectors for leakage. I
had a rubber fuel hose on my current Miata split on me one time and it
was spraying a lot of gas into the engine compartment.
This could be the same thing but a very small leak. It obviously would
not take much to have the interior reeking with gas fumes.

Oh yeah, I would look closely at the hoses coming from the fuel pump as
well.
It is on the shelf behind the seats, underneath the carpet, so a small
leak here would really smell up the interior badly.
HTH and let us know!

Usually, a slightly loose fitting on any of the in trunk hoses or the hoses
themselves turn out to be the culprit.
The gas tank fittings are under a metal plate which in turn is under the
rear carpet lining the fold down top storage area.
The metal plate is usually sealed so that under car fumes do not seep into
the interior.
Is there any gas smell under the hood or under the car?

That sounds more like. It is definitely not coming from under the hood.

Don't believe the trunk smells, but I'll check that also. Gas smell is
inside the car only and seems to be coming from the area behind the
seats.

If it is coming from this area, the carpet probably smells strongly of
gas, more so than the rest of the interior. It is not too hard to pop
out the carpet fasteners, peel the carpet forward and take a look.
Like Chuck said, this could also be the fuel pump seal, which
immediately surrounds the fuel hoses.
This rubber seal is all that is keeping the gas fumes in the tank from
entering the interior. I have never seen one go bad, but it is possible.
If there is no smell in the trunk or under the hood, then either the
fuel pump seal or the fuel pump hoses would definitely be the best guess.
Good luck!

Obviously, a fix of the cause is needed. Then, since the smell is evidently
coming through the car body metal--
Check for rust pinholes, etc. on the rear deck and top wells, and missing
sealant around the edge of the tank access plate.
The top tank gasket is also suspect. (It is between the top plate of the
fuel pump and sender assembly and the tank body.)
Since this is a 99, it may have had the pump and sender assembly removed at
one time to correct a known problem with the fuel pressure bi-pass valve
mounted on the pump and sender assembly. In some parts of the US, gas tank
pinholing is not unknown. This is usually a result of winter chemicals on
the road, and poor plating on the tank.

I bought the car new and I live in Florida. No rust, and no work done
on the fuel system. Like I said, it seems to be coming from behind the
seats. I will look for the cause on Saturday.

I just recently noticed a smell of gas in my '99 also. It seems to be the
worst after I fill the tank
and dissipates after some fuel is used. This is also a car that has only
been driven in Florida and
is garage kept.

Do you tend to fill up to the very top or stop the pump at the first
cut-off? Just checking because the former can cause this smell.
In any case, the most likely source of the smell is the hose from the
gas tank opening.
If you do not top it all the way off when filling up, then this hose may
need to be replaced to eliminate the gas smell.
