?My 2000 EVC has a strong raw gasoline smell after driving on a hot day at altitude after stopping. I've been unable to localize the smell precisely, but it's definitely raw gasoline (not unburnt from the tailpipe), and definitely outside the vehicle.

A few years ago, after the van was over-filled in Oregon (where you can't fill your own tank), I had the subsequent problem where I could not fill the gas tank because the gas pump would keep shutting off. That problem has since resolved, and these days I have no trouble filling the tank to full. It's likely the over-fill saturated the evap. canister with liquid gas for a time.

So where are the fumes coming from?

My theory is that the evap. canister is basically OK now (otherwise, I wouldn't be able to fill the tank), but that parts downstream from that may be malfunctioning.

The N80 valve is about $50, so I'm thinking of just replacing it.

I have no OBD-2 codes or CEL, but my understanding is that blockage of the N80 system may not throw a code.

I would replace the evap canister, but these are no longer available.

Any advice?

At about 30k miles my '97 EVC had a couple fuel injectors replaced.
The dealer tech did not install them correctly, resulting in their leaking.
Resulting in an engine bay fire when I next started it.
I put it out before the fire department arrived, towed to dealership.
They accepted responsibility, kept it six weeks and replaced almost
everything in the engine bay except the block and repainted the hood and grill.
You don't want a fire.

It could also be a leaky vent hose. Leaking high pressure fuel lines or injectors are also possible.

I appreciate the cautions, and I suppose it's possible that leaky injectors could do that, but seems more likely to be the evap system based on reading prior experiences about these symptoms.

Also, I did take it to the mechanic (VW dealer) a few years ago, and they couldn't find anything wrong at that time. But of course, they are located in a cool location at sea level. This gas smell has been going on for years, but only happens when hot and at altitude. Also, it's most noticeable after you turn off the van, which seems inconsistent with leaking injectors. There's absolutely zero raw gas smell in day-to-day driving at sea level.

Try searching this group for 'charcoal' and also take a look at this link:

Could be as simple as a failed evap purge regulator - certainly the symptoms match.

Sorry to join the party late here, been running behind on things recently. ?By chance are you a member in groups-io of?[Rialta-Tech-IO] Rialta-Tech? ?It’s a Rialta group, and Rialta’s are a Eurovan based vehicle. Other than Anti-lock brakes and fuses and a few other things, from the dash forward they are a Eurovan, including the Evap system. ?The reason I mention this is because they have described this exact issue countless times over the years. ?I haven’t followed it too much since I’ve never had the issue. ?It includes fuel smell, what appears to be boiling fuel in the tank (some cases), altitude related often, the N-80, hot temps often, the charcoal canister, and often fuel filling issues and pressure in the tank. ?I would suggest joining it and using the SEARCH feature to find some of the cases. I first would go to the section on “# Hashtag” and look for “?#EVAP_System ” .??There are 11 pages of topics on this and I’m willing to bet your answer is in there.??If you just ask without searching. You may find you’ll get the topic locked on you as it’s been discussed ad nauseam. ?It’s a great forum for Eurovans but be aware and courteous as it’s not a Eurovan forum per se, but they do understand we have a lot in common, and part of that is cross-common information needed to stay on the road. When appropriate (I always do so in my “signature”), what you own- an EV.
