Suspenix Fuel Tank Vent Valves

Suspenix fuel tank vent valves are replacement vent valves with grommet seals that regulate tank vapor pressure for older Ford F-series and Thunderbird models, sold as a pack of two.

These vent valves are designed to restore correct venting behavior in classic Ford trucks and select Thunderbirds. They allow fuel vapors to escape when necessary, preventing pressure buildup inside the tank that can cause fuel system performance issues. Each kit includes two vent valves with matching grommet seals and fits specific model years listed below.

Which vehicles will these Suspenix vent valves fit?

These valves are made for older Ford full-size trucks and some Thunderbirds. Confirm by matching model year and part numbers before purchase.

• Fits 1980–1996 Ford F-150 and F-250 models
• Fits 1980–1997 Ford F-350 and select Thunderbird applications
• Direct replacement for part numbers like F6TZ-9B076-AA, F6TZ9B076AA, E1FZ-9B076-B, and E1FZ9B076B

How does the vent valve help my fuel system perform?

The vent valve controls when tank vapors are allowed to vent, keeping internal pressure within safe limits. Without a functioning valve, vapor can build up or escape incorrectly, which may cause tank hard starts or fuel smell nuisance.

• Regulates vapor escape during fill and thermal expansion
• Helps prevent overpressure inside the fuel tank
• Maintains the intended behavior of the vehicle's fuel system

What should I know about installation and parts included?

Each pack contains two Suspenix vent valves and grommet seals. For easier installation, install the rubber grommet into the tank opening first, then push the vent valve into the grommet until it seats securely.

• Pack quantity: 2 vent valves with grommet seals
• Tip: fit the grommet first, then insert the valve for a snug seal
• Some vehicle variants require two valves—check your model before ordering

Will these valves work as a direct replacement for original parts?

Yes — they are designed to match the fit and function of the original equipment for the specified years and part numbers. However, always verify compatibility with your vehicle's year, make, and part number before installing.

• Engineered to match OEM dimensions and sealing interface
• Compatible with the listed Ford part numbers for direct replacement
• Recommended to compare the old valve and grommet to ensure correct selection
