Hi,

New member here and recent owner of a 05 convertible crossfire. I have a problem with a gas smell/vapors any time I put the top down or windows when driving. I get smell of gasoline immediately. The trunk is missing the liners and side covers. I do know at some point soemone drilled through the opening for the gas sensors. Hope I explained that location well enough, but it is the 5" round opening the gas sensors are plugged into the top of the tank. I'm told they were going to run some speakers wires through it. IDK. It is patched with a hard black plastic like substance just above the wires. I know gas did seep into the car at one point and saturate the floorboards. I assume that's why the liners are missing too now. I removed all the carpeting and cut out the bad areas that were full off gas. The smell went away almost immediately. However I've had the car only 2 weeks. So I just filled the tnak for the first time. There is no leaks anywhere at this time. As well a smoke test shows no leaks in engine compartment nor any fuel lines etc. This smell is more prominent when I filled the tank up. More gas more vapors right! Please help me figure out how to stop this.

 

Since you have trunk liners out already have a look at the drain hose. If there is a break in the line the fluid will go directly into the car




it is suppose to follow this path shown in red



Exit the car through a small hole behind the wheel

Ok I will check that out. Would that cause the smell to be worse if tank was full rather than say almot empty?

 

if you spill any when you fill (even a few drops) then you would smell it...

 

Sorry, forgot to mention that I got in the trunk and could smell the vapors gas from the upper top left of tank/tank shield. Again whent the car is not moving it does not smell nor does it when driving with windows and top up and lcosed. It only comes in when windows are down or top is off. Almost like the air coming into the car it sitrring the vaoprs around from trunk/gas tank where there is an air hole or something.

 

It might not hurt to replace the gas cap with a new one. If the cap isn't sealing properly it can cause the EVAP system to make that vapor smell also.

 

There is a good chance that someone has drilled into the gas tank.

 

hi new member here

The cat converter on my Ltd coupe failed, had the petrol smell, now it’s been replaced the smell has gone, tfific

 

Fine, nice to have you here on the forum, welcome, but be advised you are answering a post that is four years old. Check the date at the top of each post.

 

Welcome to the best car forum I ever belonged to. I would like to second 'zip's' suggestion, and also add you can open your own post. It would also help everyone who responds to have a little more information. Glad you got the cat fixed but just what does ' tfific ' mean? Again, welcome, and enjoy your purchase. You'll find a wealth of information from many who save gobbs of money. Oh, last bit of advice, NEVER take it to a dealership. An independant MB mechanic is best IF you cannot find the fix here for $$$$$ less cost and some time.

Four or forty years old the post is in an appropriate thread so why start another one which has no other answers?
It is not like a car parts thread which is years old.

 

Hey I know this is an old post, but I'm having the same gas smell issue on my 05 Srt6 coupe. Windows up, no smell. Windows down, horrible horrible gas smell.

Have others with this problem find fix?
