Chevy C10 Smells Like Gas? Here's the Vapor Fix

Square bodies, Action Line trucks and early C10s are some of the most popular classic trucks on the road. They are also known for something owners don't brag about: gas smell.

Why C10s are prone to gas smell

Depending on the year, C10 fuel tanks were mounted in different spots, including behind the seat in the cab on some models. Many of these trucks also have aftermarket tanks, relocated tanks or fuel cells installed during restoration. In almost every case, the tank vents to the atmosphere.

When fuel warms up, it expands and pushes vapor out through the vent. In a shop or garage, that vapor collects. In trucks with a cab-mounted tank, it can come right into the cab with you.

First: make sure it isn't a leak

Inspect the tank, sending unit gasket, filler neck, rubber lines and clamps. Old rubber hoses are a common cause of fuel smell on older trucks. If you find wet spots or soft, cracked hoses, replace them first. A liquid fuel leak is a fire hazard.

The upgrade most C10s are missing

Modern trucks control tank vapor with a charcoal canister. Vapor Trapper brings that same idea to classic trucks with a billet aluminum canister that installs in line with your fuel tank vent hose. Vapor passes through activated charcoal, which captures it before it reaches your shop or cab.

Why it works for C10 builds:

• Universal design that works with stock, relocated and aftermarket tanks

• Compatible with fuel cells and EFI conversions

• Clean 6061 billet aluminum look that fits a restored or custom truck

• Rechargeable charcoal and a lifetime warranty

Tight on space?

If you are running a bagged or lowered C10 with limited clearance, the Low-Profile Vapor Trapper offers the same vapor control in a slimmer design.

Drive it, park it, enjoy it

Your truck should be something you are excited to walk into the garage to see. Stop living with the gas smell.
