Vapor Canister Solenoid Vent 911-099 Compatible with Chevy/GMC

In this review of the Vapor Canister Solenoid Vent 911-099, the bottom line is straightforward: this replacement purge valve is for owners of mid-2000s to late-2010s Chevrolet Silverado and GMC Sierra trucks who need a direct-fit, OE-spec fix for evaporative emissions issues. The reviewer found the unit to be manufactured to OEM standard and able to replace a variety of reference numbers such as 23103351 and CPV149, which makes it a practical choice when a faulty purge valve causes rough idling, fuel smell, or difficulty refueling.

Key Features

• OE standard fit: Manufactured to meet OEM specification so it can directly replace original purge valves without modification.
• Wide reference compatibility: Cross-references part numbers like 911-099, 23103351 and CPV149 to simplify finding the correct replacement.
• Vehicle fitment: Compatible with many Chevrolet Silverado and GMC Sierra model years so it covers common heavy-duty and 1500 trucks from 2007 onward.
• Function: Controls gasoline vapor flow from the tank to the engine to reduce emissions and prevent excessive tank pressure.
• Durable materials: Constructed from ABS material designed to resist heat and aging for longer service life under engine-bay conditions.

Who It's For

The Vapor Canister Solenoid Vent 911-099 is aimed at DIY mechanics and professional technicians who need an OEM-spec replacement for evaporative emission control on Chevrolet Silverado 1500/2500/3500 and GMC Sierra 1500/2500/3500 trucks from the model years listed. It is particularly useful when a vehicle exhibits symptoms like fuel odor at the fill neck, rough idling, stalling, or a no-start after stalling that can indicate a failed purge valve.

Those who should look elsewhere include owners of vehicles outside the stated fitment years or models, and buyers who require an OEM-branded part number from a vehicle dealer for warranty reasons. Always verify vehicle information before purchasing to ensure compatibility.
