Smell is in the car all the time. Not coming from the front of the car.

I could be driving at 60 mph or idling and the interior of the car still stinks of gas.

Vents are always off.

Does this sound like cracked vent lines on the tank or evap cannister?

Would evap cannister fumes still come into the car at 60 mph?

Car has 110K miles.

 

only thing that happene when the cannister went bad on my 96 SS is the SES light came on. of course they repair guy said the inside of the cannister exploded and sent crap through the entire fuel system. anyhoo, i wouldn't think the smell would stay in the car at 60. do you have the windows down? maybe gas got spilled in the car? wish i could help more.

Windows are down at 60 and you can still smell it.

 

Did he explain how that could happen?

Weird how it could be that powerful with the windows down while moving. Evap canister is in the front of the car. Chances are with the vehicle moving and still be able to smell it the problem would be coming from the front of the car. Check everything fuel related including the connections between the hard lines beneath to the plastic lines exiting the fender.
One simple thing to check is the Schrader valve to see if it may be stuck open.

 

In front of the car? I thought it was behind the fuel door by the driver's side rear wheel?

 

You're absolutely right. My bad. Still check for fuel anomalies in the front though.

 

I remembered when I had a fuel smell problem after I would park my car or after I get gas. I had a small split in one of the vent lines on the EVAP canister. But it seems your problem is alittle different because you could smell fuel while you are driving but it is worth checking out.

 

if you keep hitting the gas pump after it clicks off to 'get more gas in the tank' then you probably filled the canister with gas. idiots here in jersey will click away and i freak on them. i wish i could pump my own gas here

any way. the tank is supposed to have an air pocket in it to allow for vapor expansion...and it will go into the evap canister. this is normal...what's not normal is the liquid going into the canister.

i still think you may have a hose leak or injector leak. if you havent messed with it and it just happened i think you should look into injectors first...look for leaks. it will be obvious

 

I have this same problem (sorry for thread necromany).

Fuel smell on my clothes after driving too and from work. (windows down in the city)

My car was garaged for over 3 years cause I had a company vehicle and poorly treated the car by doing nothing to it and just letting it sit.

Fuel pump obviously went bad and had a rat chew up some harnesses under the hood.

Had the fuel pump replaced, plugs+wires, harness spliced where needed. And of course they didn't replace the fuel sending unit because the guy thought I couldn't afford it (after spending over $2000 with him already? Com'on!!) So my guage is always full. I'm gonna check it using a multimeter and instructions from shoebox.

Anyhow. I'm not sure exactly where to start to identify why I smell like exhaust/gas on my clothes after driving the car (it's only noticeable to me, not really to others).

Also, my CAT is gutted, but I didn't have this issue over 3 years ago when I was driving the car then.

I'm planning on replacing the sending unit myself by using the trap door method, but I've only seen instructions for the pump, not sure where or what the sending unit looks like exactly or how it installs.

Any recommendations on where to start? (I'm afraid they could have broke my filler next when dropping the tank).

 

Had similar problem on 95 Z28. Evap canister is located behind LR wheel, behind inner fender cover. One of the hoses was disconnected from the cannister and laying in the frame. Reconnected and secured with a hose clamp. Problem solved.

 

Sounds like when the fuel pump was installed, they forgot to reconnect the sending unit wiring, and the hoses for the EVAP canister.

The sending unit is riveted to the side of the fuel pump support. When I bought one 10 years ago, you could only get the level sending unit by buying the complete fuel pump support assembly for about $250. By now, someone may make a replacement level sender.

Moving to "Fuel and Ignition".....

 

Might change the gas cap first,I dunno.My02.I had the same problem,but went away when I changed the gas filter.Little foggy here,too much beer.

 

I have everything you are described, please tell me you found the problem

 

Hi,

I'm not sure yet, that was a decade ago when I was home again for awhile. I've replaced the gas cap and haven't had any gas smell but haven't driven the car much. I know that I've got varnished fuel and possibly gunk in my fuel tank though. I need to drop the rear end and remove and replace it, and inspect all the lines.

The lines connecting to the canister are worth inspecting.

I've also decided against cutting an access panel. Want to do it the right way.

 

When the hose from the tank to the canister cracked, or came loose (a shop had recently pulled the tank to install a sump for a second, outboard fuel pump) the smell of gasoline was extremely strong in the passenger compartment. But only when the car was stopped, and the driver's window was partially or full open. Replacing the hose solved the problem.

Since it smells in your car all the time, there is another possibility. The metal line from the canister to the front of the car ends behind the quarter panel, near the leading edge of the door. The metal line is connected to the nylon line by a short length of rubber hose. I've seen a couple cases reported recently where that hose rotted and fell apart. That might possibly be the source of the smell inside the car.
