Hey guys so I live in Vegas and it was about 107 today. So when I turn my A/C on I can smell very strongly raw gas in side and out side the car? Mostly out side the car though. I checked and there is no loose lines or any of that. So I do not know what is causing this? Any ideas?

 

Check to see is the oil filler cap is still inplace.

 

Was not loose and it also does not do it all the time it seems like only when its real hot and the A/C is on more than half way.

 

It might be the EVAP canister.

 

okay so thanks to your thread and many other i have deduced the problem on my end.

step one to figuring out if the problem is the same as mine!
-smell your engine bay and all around the compartment, if the fuel smell is not coming from this area it is not a fuel pump related issue!
TWO
-immediately after turning off your car(or when you notice the smell), smell all around your fuel cap(but don't get high)and see if the stench is strongest here... if the smell seems to be emitting from this area YOUR FUEL CAP MAY BE BAD! next, after deducing that the smell is strongest where you refuel open the door and put your ear close to the fuel cap(without un screwing the cap), if you notice a faint seeping sound (as in pressure leaking from fuel tank) YOUR FUEL CAP IS DEFIANTLY BAD!

i noticed that this only happens after pressure has built up (which is much valued) in the gas container leading to a leak, which makes sense for those individuals (such as me) who live in hot climate areas.

i was very annoyed at this issue and noticed my fuel economy had substantially dropped! my mile per gallon were going down hill and when gas is much valued you don't want this! i noticed the smell was not emitting from my engine bay, and more so from where the fuel cap is located(behind the driver-side rear wheel)! i also noticed a small *fissing* noise from my fuel cap which sounded like a small leak (say from an air compressor with a leaky valve) i then pulled off my fuel cap and noticed that the main seal had two minor fracture cracks in them, which would easily mean that gas could escape due to increased pressure build up. (not liquid gas but gas gas... you know what i mean, like a co2 gas.. yea!) anyways i found that the solution to this issue was as easy as .... you guessed it ... a new fuel cap! their about $23.50(+tax) at your local Honda dealer[part number '17670-SM4-A04']... may be less if you live near an on-line OEM parts dealer due to low shipping rates, but in my case more expensive on-line! so please spread the word since many seemed to be confused and without an answer to this issue!

but this was in my case and seems to be that of many others as the smell is emitting from the rear driver side region!
