Due to customer demand - here at Shop48 we are always thinking of innovative ways to eliminate the "unwanted gas smell" from your garage or storage area. We developed this 4-inch by 1.5-inch diameter Vapor Trapper for small engines and VERY tight spaces. This was originally designed for home generators and small engine stored in your garage. This small vapor trapper functions exactly like our standard size models just with less charcoal capacity. 
 
If you have a small engine or fuel stored in your garage that is creating that unwanted fuel smell - this Vapor Trapper is your answer! 
 
Note - we typically add a barb fitting to the fuel cap of your gas tank and run the vent line to the Vapor Trapper. You can get very creative with the installation with this little one!
