How to Install Your Vapor Trapper in 4 Simple Steps

Installing a Vapor Trapper™ is quick, easy, and makes an instant difference in eliminating fuel odors. Whether you’re working on a classic car, ATV, boat, or daily driver, you don’t need special tools or advanced skills — just follow this step-by-step guide.

Step 1: Gather Your Tools & Parts

  • Vapor Trapper canister

  • Billet clamps or mounting hardware

  • Appropriate sized fuel vent line

  • Screwdriver or socket set (depending on clamp type)


Step 2: Choose the Right Mounting Location

Choose a place preferably as high as possible above your fuel tank. Make sure it’s away from excessive heat sources or moving parts. We suggest having a minimum of 8" clearance if possible. On most cars, under the rear window package tray is an ideal location as it keeps it as high as possible to prevent liquid fuel from getting into the Vapor Trapper charcoal media inside.


Step 3: Install the Canister

  • Secure the billet clamps (or other mounting brackets) to your chosen surface.

  • Slide the canister into place and tighten the clamps.

  • Ensure it’s snug but not overtightened to avoid damage.


Step 4: Connect the Vent Line

  • Attach your fuel vent line from the tank to the inlet on the Vapor Trapper.

  • Secure with hose clamps.

  • Double-check that the outlet is unobstructed so air can pass through the filter.

  • Run the exit line to exterior of the car if the Vapor Trapper is mounted in the trunk compartment.


Pro Tip: Check your canister’s charcoal media every 6–12 months, depending on usage, for peak performance.


It's not what you get when you buy a Vapor Trapper for your prized possession - it's what you don't get: THAT UNWANTED RAW GAS SMELL!
