dwuollet Posted October 3, 2010 Share Posted October 3, 2010 I've done abunch of searching and can't find what I'm looking for. There is a gas smell inside the cabin of my wagon. It's a 85 Weber conversion, it smells like gas when driving and after it sits, no leaks i can see under the hood and it doesn't smell like gas under there. no puddles under the car. Doesn't smell outside the car. Runs fine. Any ideas? It really sucks to have drive with the windows down in the cold, luckily we haven't had too much rain yet.

nipper Posted October 3, 2010 Share Posted October 3, 2010 Slight fuel line leak, but it would start by looking at the charcoal canister, purge valave, evap system. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted October 3, 2010 Share Posted October 3, 2010 Slight fuel line leak, but it would start by looking at the charcoal canister, purge valave, evap system. This one has none of that stuff - it's a Weber swap. Check the fuel lines at the firewall? Maybe a hose clamp is leaking and the fuel is running back into the cabin there? Are you sure it's not an exhaust leak that you smell? Sometimes when running rich (choke on, etc) exhaust can smell of gasoline.... That's weird - if you get a chance to bring it by I can look it over. GD Quote Link to comment Share on other sites More sharing options...
dwuollet Posted October 3, 2010 Author Share Posted October 3, 2010 I thought of the running rich angle too, I haven't changed anything carb wise and the choke is all the way open. I'll check the line at the firewall, sounds likely since the car smells whether it's running or not. thanks Quote Link to comment Share on other sites More sharing options...

GeneralDisorder Posted October 4, 2010 Share Posted October 4, 2010 That's right - almost forgot about that thing. It's a vapor seperator tank. Definitely could be something to look at. Is the smell stronger in the back of the car? GD Quote Link to comment Share on other sites More sharing options...
ivantruckman Posted October 4, 2010 Share Posted October 4, 2010 it there any rust. some fuel lines run under the back seat, or along the rockers , well here in the rust belt any way , i just started sniffing around, i didnt sniff the seats however Quote Link to comment Share on other sites More sharing options...
DaveAP Posted October 5, 2010 Share Posted October 5, 2010 My '78 brat had the same problem. I noticed a wet spot on the lower weld for the back right fender. Opened up the panel and noticed a vent line ? end was wet. I ended up daylighting that hose and all was well. (It didn't drip all that much) dp Quote Link to comment Share on other sites More sharing options...
kanurys Posted January 11, 2011 Share Posted January 11, 2011 I'm having a similar problem. The interior smells of gasoline weather it has been sitting or while driving. It started abruptly a week ago and is continuous. We've been having sub-zero temps. Maybe that cracked that rear vapor canister or something else plastic. My EA82 is weber-ed and is stripped of all the charcoal canister stuff and what not just like dwuollet. There are also no visible signs of fuel leaks on any of the rubber fuel hoses. I'll check under the back seat and the canister in the rear of the car... On another note, when I pulled it into my warm garage and it sat for a while, the smell had mostly gone away. I'm thinking it has something to do with the extreme outside temps. Should the fuel return lines and the return vent line by the brake booster be capped off? I figure cap the fuel return, but let the vent be open to breath. What do you guys think? Quote Link to comment Share on other sites More sharing options...
Yo'J Posted January 12, 2011 Share Posted January 12, 2011 I left my charcoal canister with my weber, for the vent. Gas expands and contracts with the temp and I wanted to be safe. I also put a return on the carb. Could it be pressure related? Are the vent and return lines just kind of pointed up, so gas might drip in, capped or not?

kanurys Posted January 12, 2011 Share Posted January 12, 2011 Mine are just sticking out of the firewall uncapped. I was toying with the idea of reinstalling the charcoal canister with the weber and using the vent line from the tank, again. Also I have a fuel fitting with a 1/8" barb for the return line to install that, too Do you guys know wich one is the fuel return hard line and the vent hard line next to the brake booster? I can't remember. Quote Link to comment Share on other sites More sharing options...

I had the same problem on my stock EA81 wagon, turns out the plastic canister in the back had a broken nipple. I got another one but as my car is an odd year I had to retrofit a bigger line size canister. Kinda annoying but not difficult. Quote Link to comment Share on other sites More sharing options...
kanurys Posted January 15, 2011 Share Posted January 15, 2011 From what I can tell, fuel vapor is not coming from the rear canister. I think it's accumulating from the weber vapor vent and the problem is exacerbated by the cold temps. This is all the more reason to put the charcoal canister back in. I think I'll actuate it off of the EGR vac line. Yo'j, how do you actuate yours? Quote Link to comment Share on other sites More sharing options...
Yo'J Posted January 15, 2011 Share Posted January 15, 2011 I have mine off manifold vacuum, it should be able to accumulate safely and get pulled into the motor to get burned at low rpm is what my original thinking...I think, was, I have to go look.

kanurys Posted January 16, 2011 Share Posted January 16, 2011 Cool, thanks Yo. I was thinking that the EGR activates when the engine isn't in a sensitive state, off of the Weber. This is also a good time to introduce the vapors stored in the charcoal canister. So far, plugging the vent port on the carb (I know, not a great long term idea) has stopped the fuel smell.
