Title: Vapor Trapper
Post by: chrisbutnut on February 24, 2025, 04:18:21 PM
Has anyone used a Vapor Trapper in line of the fuel tank vent to eliminate gasoline smell?  I found their advertisement in the Hagerty magazine.

Starting at $300?  I would have to search but there was a maybe Ford one that was like $30 and easy to mount.

Putting an exhaust fan in the garage seemed like a better idea.  Maybe not over-filling the tank.  In the summer I get the gasoline smell if I overfill my gas tank.

I enjoy that slight smell of gas and oil in my garage, there is nothing else like it - lets everyone know there is a real car in there and not a plastic plug-in.

Nonetheless, if the car is old enough, you might eliminate the gas smell but still have the smell from the draft tube.

Just thinking out loud.....  why would the level effect the smell?   Assuming that it wasn't so high that it was expanding and spilling out somewhere?  I would think if anything the higher level may leave less areas exposed to air?   Basically if there was no air space there would be very little surface area to be exposed to the air?  Again assuming its not just spilling out.

Once there is any air space with most tank designs the surface area is going to stay about the same throughout the range of levels so why would the smell change just based on the level?

I just filled up today, and notice quite a bit of gas leaking when I got home and parked in my driveway.  I figured the attendant had overfilled the tank, if that's possible.  I decided the best solution was to go drive around and burn some of the fuel off.  I stopped at a muffler shop to have them look at my resonator, which has a couple of pin holes in it.  They put the car up on a lift to do that, and I was able to get under and see that the fuel seemed to be leaking from the area where the vent tube goes into the tank.  Because the vent tube attaches to the back side of the tank on the top, I wasn't able to see exactly what the problem was.  The vent tube looks like it's metal, and it goes into a metal gas tank.  I'm not sure if there is a loose connection or a crack or what.  It's obviously something I need to get addressed.  Regardless, the fuel odor in the garage is almost unbearable when the tank is full of fuel (especially to my wife).  I'll address the leak first and see if that solves the problem.  If not, I'll try some sort of a filter on the vent tube.

Not sure what year your car is, but sounds like the neoprene connecting hose that attaches the vent pipe to the tank has become cracked, or broken.

On my '72 Eldo, I had to replace all the neoprene connectors.

I suggest that you begin spraying the bolts for the retainer straps and wire wheel them to get them ready for when you decide to pull the tank down. It's not difficult.
