XTPTFABS Fuel Tank Vent Valve for 1985–1992 Camaro & 1985–1989 Firebird — Direct OEM-Fit, Reduces Fuel Odor

XTPTFABS Fuel Tank Vent Valve replaces HT10033125/10033125/10029145 to restore proper tank ventilation and reduce fuel odor in stored TPI/TBI Camaros and Firebirds.

This replacement vent valve is designed for classic GM V8s with TPI and TBI fuel systems, specifically fitting 1985–1992 Chevy Camaro and 1985–1989 Pontiac Firebird 5.0L and 5.7L engines. Built from durable materials, it provides a direct OEM-fit substitute for the original part numbers HT10033125, 10033125, and 10029145. The valve helps vent trapped gases from the fuel tank while preventing liquid fuel from entering the EVAP line, making it a practical service item for enthusiasts who store or regularly drive older vehicles.

How does this valve improve fuel tank ventilation?

The valve opens and closes to allow tank vapors to escape into the EVAP system during normal operation while preventing fuel from flowing into the vent line. That controlled venting helps maintain correct pressure balance in the tank and limits strong fuel odors in garages or enclosed spaces.

• Direct-fit design matching OEM mounting points and hose connections
• Durable construction resists fuel exposure and heat
• Prevents liquid fuel intrusion into EVAP lines
• Compatible with TPI and TBI-equipped 5.0L and 5.7L engines
