Sea-Dog Zinc Gas Tank Vent

Sea-Dog Gas Tank Vent provides controlled airflow and pressure relief for portable fuel tanks. Constructed from chrome-plated die-cast zinc with an integral 5/8 inch hose barb, this vent maintains fuel flow during filling and use and routes fumes outboard for safer onboard conditions.

Problem: fuel delivery can be interrupted by vacuum build-up and tank pressure changes, and fumes or blow-back can enter the boat. Solution: this vent compensates for tank level changes from consumption and thermal expansion while acting as a pressure release to prevent spills and backflow.

• Prevents vacuum build-up and maintains consistent fuel flow
• Chrome-plated die-cast zinc construction for mechanical strength
• Integral 5/8 inch hose barb for secure vent hose connection
• Directs fumes outboard to reduce onboard vapor accumulation
• Helps reduce fuel spills and blow-back during filling and use
• Recommended for freshwater use per manufacturer guidance

Compared to basic plastic vents, the die-cast zinc body offers greater structural durability under normal freshwater conditions while chrome plating provides surface protection. Install the vent with a 5/8 inch vent hose routed outboard and secured to prevent kinking.

Manufacturer Sea-Dog part 352100-1. Use this vent as a replacement or upgrade for portable gas tanks where controlled venting and outboard fume routing are required.
