Podavelle AN8 Inline Rollover Breather Valve, AN8 Female to AN8 Male, Aluminium Black, Gravity-Check

Podavelle's AN8 female to AN8 male inline rollover breather vent valve is a compact aluminum fitting that lets fuel tanks breathe while automatically stopping vent flow if the vehicle rolls over. This compact inline valve pairs AN8 female and AN8 male connections in a billet 6061-T6 aluminum body with a black anodized finish for corrosion resistance and long-term durability. It contains a gravity-activated check ball that prevents fuel from escaping through the vent when a vehicle is inverted, while allowing normal pressure equalization during everyday driving. The unit is compatible with gasoline and alcohol-based fuels and is intended for integration into fuel tank vent systems; professional installation is recommended.

How does this valve protect against fuel loss in a rollover?

The valve uses a simple gravity-operated check ball that moves to seal the vent passage when the vehicle is upside down, stopping liquid fuel from exiting the tank through the vent line. In normal orientation the ball rests open, so vapors and air can pass freely.

• Gravity-activated internal check ball seals vent when inverted
• Inline arrangement sits within the vent line for direct protection
• Compatibility with common fuels prevents chemical degradation of components

Will this fitting maintain proper tank breathing and pressure balance?

Yes — during regular operation the valve permits airflow into and out of the vent line, preventing vacuum or pressure buildup inside the fuel tank. That helps consistent fuel feed and avoids stress on tanks or hoses caused by trapped pressures.

• Allows free venting under normal vehicle orientation
• Prevents tank vacuum that can hinder fuel pickup
• Works passively without electrical power or moving external parts

What materials and finishes ensure durability and fuel compatibility?

The body is machined from 6061-T6 billet aluminum for a strong, lightweight construction. A black anodized surface treatment improves corrosion resistance and wear life, while internal components are chosen to resist deterioration from gasoline and alcohol-based fuels.

• 6061-T6 billet aluminum for high strength-to-weight ratio
• Anodized coating for corrosion and abrasion protection
• Fuel-compatible internal components suitable for ethanol blends and gasoline

How do I install and size this inline rollover vent valve?

This valve is sized AN8 female to AN8 male and is designed to be placed inline within an AN8 vent hose assembly. Because installations vary, professional installation is recommended to ensure proper hose routing, secure fittings, and leak-free connections.

• Connector type: AN8 female to AN8 male inline configuration
• Intended for use in vent lines rather than pressurized fuel feed lines
• Professional installation advised; no instructions included

This Podavelle inline rollover breather vent valve is ideal for vehicle builders, race teams, and enthusiasts who need a reliable, compact vent solution that balances breathability with rollover protection. Fit it into fuel tank vent systems on custom builds, motorsport applications, or any installation using AN8 vent plumbing where preventing vent-line fuel loss is important. Because correct placement and secure hose connections are critical, have a qualified technician integrate the valve into your venting system to ensure safe, reliable operation.
