3/8" barb x 1/8" NPT brass fitting for filler neck vent lines. This fitting is ideal for applications where the original fuel system used a vented cap but lacks a dedicated tank vent—common in early vehicles like 1964–1970 Ford Mustangs and many 1950s–60s models.
Installation is simple: remove the filler neck, drill and tap it to accept this fitting, and install it to create a proper vent path. Then route the vent line to the Vapor Trapper™ and out to the atmosphere. Be sure to replace the fuel cap with a non-vented version for optimal performance
A few years back, Owner Tom Mischke was presented with a challenge when a customer brought him a 1962 Jaguar that was emitting a strong gasoline odor. Looking at the fuel tank, Tom sought to find a way to capture the vapors that were being vented directly into the atmosphere. Knowing that activated charcoal is used to capture odors, Tom looked everywhere for an existing charcoal canister that could be adapted to automotive use. When he couldn’t find one, he decided to make it himself.
Our most recent innovation, Vapor Trapper, is poised to change the classic car hobby in a major way. Before EPA regulations mandated closed-loop fuel systems, gasoline vapors were an annoyance that had to be tolerated by every auto owner. Today, people just expect their vehicles TO NOT SMELL LIKE GAS and if they do – it’s a sign that something is terribly wrong! But if you own a vintage car, truck, or even a modern-built hotrod with a new fuel-injected engine, you probably go out into your garage, and it smells like gas.
The result is Vapor Trapper, a universal billet aluminum charcoal canister that traps gasoline vapors before they can escape from the fuel system. Easily installed anywhere above the fuel tank level, the Vapor Trapper absorbs gas odors while allowing the fuel tank to vent normally. The charcoal lasts for a long time. When it becomes saturated, simply unscrew the top, replace the charcoal, and the Vapor Trapper is ready to go. Vapor Trapper is now installed on every car that passes through Tom’s shop.
