Why Does My Chevelle Smell Like Gas? A Muscle Car Owner's Guide

There is nothing like walking into the garage and seeing a Chevelle sitting there. What you do not want is to be hit with a cloud of gasoline smell every time you open the door.

The usual causes

Gas smell in a Chevelle, or almost any classic muscle car, usually comes down to two things: a leak, or fuel vapor escaping from the tank vent.

Leaks can come from:

• Aging rubber fuel hoses

• A worn sending unit gasket

• A loose or cracked filler neck connection

• A carburetor that is overflowing or leaking at the base

If you see or smell liquid fuel, fix it before driving the car again.

Tank vapor: the smell that won't go away

If everything is dry, the smell is probably vapor. Muscle cars of this era vent their fuel tanks to the atmosphere. When the fuel warms up during the day, or the car is parked after a drive, vapor pushes out through the vent. In a closed garage, it builds up overnight.

High-performance fuel, warm garages and long periods of sitting can all make the smell stronger.

A modern solution with the right look

Vapor Trapper is a billet aluminum charcoal vapor canister that installs in line with your fuel tank vent hose. Activated charcoal inside captures fuel vapor before it escapes. The machined 6061 billet aluminum body looks right at home on a muscle car, whether it is a numbers-matching restoration or a pro-touring build.

Chevelle owners like that Vapor Trapper:

• Works with stock tanks, aftermarket tanks and fuel cells

• Works with carbureted and EFI setups

• Has rechargeable charcoal, so it does not need to be replaced

• Is made in Arizona and backed by a lifetime warranty

Keep the muscle, lose the smell

Your Chevelle should make the neighbors jealous, not make your family complain about the garage. Stop living with the gas smell.
