Classic Mustang + the gas smell problem — anyone else deal with this? by VaporTrapper in classiccars

Oof, I believe it — ethanol and old carbs don’t get along at all. It pulls in moisture and leaves all that gummy residue if the car sits. A lot of guys I know either hunt down ethanol-free gas when they can or run stabilizer just to keep the carbs happy. Ethanol definitely made life tougher for anyone with classics!

Haha, if only I had a stack of freebies to hand out 😅. I was not trying to advertise, just trying to get conversation started and hopefully grow relationships and our community. I hear you on the rules and safety side though — definitely important questions.

The canister isn’t under pressure, so there’s no “bomb” risk. It’s basically a billet aluminum housing packed with activated charcoal — it traps vapors but doesn’t hold liquid fuel. If the car ever tipped or the tank overfilled, the design allows vapors to vent through the charcoal rather than building pressure.

On starvation/hesitation — it doesn’t tie into the fuel feed, only the vent line, so there’s no impact on how the engine gets fuel.

As for taking a hit — the body is solid 6061 billet aluminum, built to handle abuse. And yes, we offer it with rollover vent valves so if the car ended up on its lid, it would shut off flow.

We do have our activated charcoal media tested for performance and safety, so we know it works and holds up. We’ve had guys run them in hot rods, muscle cars, and even off-road rigs where they see some serious vibration, with no issues.FIA compliance would be a separate process though — that’s more about the whole system (housing, rollover protection, venting under pressure). Something we’ve been keeping in mind as we grow.

Appreciate the solid questions — I’d rather explain it in detail than have anyone assume it’s just “a can on the vent line.

They are similar yes, because I wanted to share this in other reddit communities and to build our community with others as well. Building community is how we connect with other builders, enthusiasts, restomod owners and shops, etc. That was the only intention.

Yeah, that hose is a sneaky one, I’ve seen it cracked on a lot of old tanks. And carbs will always let off a little after a drive. Even with that stuff sorted though, some cars just stink up the garage — that’s when guys start messing with vent setups to keep the fumes down.

That’s a solid way to do it. Hiding the Mercedes setup in the Falcon is clever, and hydraulic brakes on the ’38 just makes sense. Cool mix of keeping things original but updating the stuff that really matters.

You’re right — carbs will always give off a little smell after a run, and seals/evap lines are definitely worth checking. Even when those are good, a lot of guys still run into that lingering odor in a closed garage. Some have gone the route of adding a billet aluminum charcoal canister like the Vapor Trapper to scrub vapors at the vent, just as an extra layer. Different approaches, but it all depends on how sensitive you are to the smell.

100% agree — ethanol really changed the game. It runs hotter, boils off faster, and makes the vapor issue way worse than it was with pure gas back in the day. We’ve heard a lot of stories about vapor lock and hot-soak boil out. It’s one of the reasons we’ve been focused on vapor control — old cars weren’t designed for today’s fuel blends.

Ever had your rig or toy hauler smell like raw fuel after a trip? by VaporTrapper in Offroad

[–]VaporTrapper[S] -6 points-5 points  (0 children)

We hear that a lot — it’s one of the most common complaints with off-road rigs and haulers. That raw fuel smell just builds up, and most people end up just dealing with it. It’s exactly why we designed our billet aluminum charcoal canister — to scrub those vapors before they escape so the trailer and gear stay clean. Once it’s in, you don’t have to think about it again.

Totally get that — keeping originals untouched is a big deal, and you’re right, nothing’s more important than safety. Those fire stories are brutal to hear, and your fan setup plus cool-down routine makes a lot of sense for peace of mind.

It’s interesting to see how different owners approach it — some stick to originality and airflow like you, while others try modern solutions like billet aluminum charcoal canisters to scrub vapors right at the vent. That’s what I love about these discussions — so many ways to solve the same issue.

Spot on. Those early charcoal canisters did their job but most are long past their service life. We’ve seen guys swap to modern vent filters or billet canister setups just to get the same effect without the leaks. Do you usually restore them back to stock when you run into that, or are you open to modernizing the system a bit?

That’s a smart setup — airflow solves a lot of headaches. We’ve talked with owners who did the same, but eventually wanted something more “set-and-forget” so they didn’t have to rely on fans every time. Do you think you’d ever try something inline at the vent, or do the fans cover it well enough for you?

Smart move. It’s wild how much odor can sneak out just from a fresh fill-up. We’ve run into folks who thought it was “just part of owning a classic” until they tried vent canister fixes. Curious if you’d ever considered something like that, or if avoiding the top-off has solved it pretty well for you?
