strong gasoline smell inside car
hey all,
I have a strong smell of gasoline inside the car (running or not)... The smell is so bad that after just a short ride, my cloths smell of fuel. Driving with the sunroof open helps - fresh air...
I recently replaced my fuel filter, vacuum line and fuel pressure regulator. I do not see any leakage of fuel underneath the car....
any advice is greatly appreciated.

Maybe the tank gasket went bad? remove the rear capet in the cargo bay, you'll find a black fire proof cover on top of the fuel pump (fuel tank). The cover gasket maybe bad and double check there for bad hoses while your at it.

Did you recently fill your tank with gas?
There is an overflow tube that runs from near your gas cap through the inside of your car and out the bottom, by your rear wheel. Maybe it came off and dumping fuel into your rear hatch area.
My .02 worth.

In the older 944's the vent tubing is the cloth coverd rubber. This has a propensity to crack as it makes the 40 degree turn from the gas cap area and across the top of the fuel tank to it's attachment point on the far side.
I've removed the cover on the filler tube assembly and inserted a bent piece of copper tubing in mine with a couple of clamps. The later model 944's have the better tubing and do not crack.
Still you need to check the fuel rail while the car is running to make darn sure that the rail has not cracked or an injector top o-ring is not leaking. An engine fire make a parts car real fast.

I too had the smell of gas in my '84 after every time I topped the tank. If I didn't top it, no gas odor. I checked the drain in around the gas cap with no luck. I pulled-up the rear deck carpeting and insulation to get at the rubber access cap that covers what I believe is the sending unit for the fuel tank. The area around the top of the tank was damp with fuel. It turned out to be some cracked rubber tubing atop the tank. I really couldn't get to it without dropping the tank.

All of the help given so far in this post are good points to check. BUT ,I IMPLORE YOU TO CHECK THE FUEL AND HOSES FIRST AS THEY WILL CAUSE A FIRE. Then do all the other stuff the guys have pointed out. Good luck

if rail/hoses/injector seal is leaking you'll have a pretty good stream of fuel coming out. pop the hood with the engine running, you'll see if there's a problem, theres ALOT of pressure in the fuel system... at least there should be.

Just my .02
After I checked and replaced just about every piece of fuel line / hose in the rear of the car (definitely the source) I discovered that the weight of the California no-emissions fume sucking fueling nozzles had elongated the round fill neck. Even the new fuel cap could not seal the filler neck. Some VERY judicious re-rounding of the filler neck (a B*TCH to replace) solved my problem. Figured if I had to replace it anyway, I might as well try to straighten it back into a round inlet rather than the ovally one.
I now support the nozzles while filling the tank.
