AIKEPT EVAP Vapor Canister Replacement for GM SUVs & Trucks — Model 911-199 / 12573649, Direct-Fit OE-Equivalent

The AIKEPT 911-199 EVAP vapor canister (12573649 / 22963841) is a direct-fit replacement that traps fuel vapors to restore proper EVAP system function on compatible GM SUVs and trucks.

This replacement EVAP canister is designed for a range of GM vehicles — including Cadillac Escalade, GMC Yukon, Chevrolet Avalanche/Suburban, and Hummer H2 — and mirrors original-equipment specifications for a straightforward swap. Built to work with the canister purge valve and other EVAP components, the unit helps control evaporative emissions, reduce fuel smell, and re-establish correct system pressure when the original canister becomes saturated or damaged.

Will this canister fit my vehicle model and year?

AIKEPT engineered this vapor canister as a direct-equivalent for specific GM models produced mainly between 2004 and 2016. Check the vehicle engine size and part numbers to confirm compatibility before purchase.

How does this canister interact with the EVAP system and engine codes?

The canister captures fuel vapors from the tank and holds them until the engine’s purge system draws them into the intake for combustion. A failing canister commonly triggers evaporative emission fault codes (such as P0440–P0453), so replacement often cures those codes when the cause is a saturated or cracked canister.

• Captures and stores fuel vapors for later purge
• Works with purge valve and venting lines to maintain system balance
• Replacing a damaged canister can clear EVAP-related check engine lights

What are the installation and quality features I should expect?

This unit is manufactured to match original equipment fit and mounting points for an easier installation. Materials and port locations follow OE guidelines so hoses and brackets align without modification on compatible models.

• OE-equivalent design for bolt-on replacement
• Standard ports positioned to accept factory lines and clamps
• Durable canister body and connections resist normal under-vehicle exposure

When should I replace my EVAP canister?

Replace the canister if you detect persistent fuel odor, failed EVAP system diagnostics, or codes pointing to purge/vent problems. Regular inspections during routine service help catch cracks, saturated charcoal, or damaged fittings before they cause drivability issues.

• Replace after recurring EVAP codes or failed emissions tests
• Swap if visible damage, cracks, or fuel saturation appear
• Recommended when purge function is compromised or odors are present
