I keep getting a gas smell in my '00 Millenia when I'm in stop and go traffic or just running around town. Does anyone know what this is and how to fix it? My Mazda dealer could not find anything.

 

That could be coming from many places. Is there any places on the motor that seem really clean, if so they are probably getting gas on them.

Fuel pressure regulators are made to increase fuel pressure with load, you will only see load when driving. Perhaps the leak goes away when you are looking for it, but then comes back when driving.

 

Haven't seen anyplace that is cleaner than the rest but will keep looking. Thx
