Marine Fuel Tank Vent

Key Features

• Chrome-Plated Aluminum Body – Corrosion-resistant, rust-proof, polished finish; far more durable than plastic vents in saltwater environments
• Stainless Steel Mesh Screen – Blocks insects, debris, and water ingress while maintaining free bidirectional airflow
• Bidirectional Venting – Allows air in as fuel is consumed (prevents vacuum/tank collapse) and releases pressure as tank heats up (prevents vapor lock)
• Rubber O-Ring Seal – Deck-mount O-ring creates a watertight seal at the hull surface; prevents water ingress around the fitting
• Straight or 90° Elbow – Straight for vertical tank installations; 90° elbow for tight spaces or horizontal hose routing
• 2-Vent or 4-Vent Options – 4-vent models provide higher airflow capacity for larger tanks or high-consumption engines
• 16mm Hose Barb – Fits standard 16mm (5/8") marine fuel vent hose on all models
• Wide Application – Boats, yachts, pontoons, RVs, personal watercraft, aluminum and fiberglass hulls

Solves These Common Problems

• Engine hesitation or stalling from fuel starvation caused by tank vacuum
• Vapor lock from pressure buildup in a sealed or poorly vented tank
• Plastic tank walls collapsing inward as fuel is consumed
• Insects and debris clogging the vent and blocking airflow
• Corroded or cracked plastic vents failing after one season

Straight vs. 90° Elbow — Which to Choose?

• Straight: Best for deck-top installations where the vent hose runs straight down into the tank; most common configuration
• 90° Elbow: Best for tight spaces, side-of-hull installations, or where the hose must exit horizontally; prevents water from entering the vent opening directly

2-Vent vs. 4-Vent — Which to Choose?

• 2-Vent: Sufficient for most recreational boats and smaller tanks up to ~100L
• 4-Vent: Higher airflow capacity; recommended for larger tanks, high-consumption engines, or hot climates with significant thermal
