Raw Fuel Smell Underhood?

93 Cobra needs input · 04-15-2002, 09:24 PM

I have a very strong fuel smell under the hood on the passenger side of my Cobra near the mass air meter. It just started doing it today and I think it is because it is 90 degrees outside. Is there a fuel return line that might be venting somewhere close? I checked my fuel lines and regulater and there are no leaks. It was hard starting the car also, quit a couple times. Seems real rich to me. Does anyone here have any suggestions? Thanks!

The raw fuel smell might be coming from the canister purge system. It's a carbon (gray) looking cannister that is on the passenger side of the front end. It's located next to the header. This system is used to purge the fuel system with gas fumes at startup, I believe. Also, check your injectors and fuelrails for any leakage. Good luck!

That sounds like the exact area and most likely the smell I didn't know about that purge canister. I had just filled the tank completely full about 1/2 hour before the problem. I checked all other fuel areas and found no leaks, I hope that is my problem! Thanks for the info.
