Perko vented straight-neck gas fill for 1.5" hose — White polymer, flip-top cap, flame arrestor

Perko 1319DPGWHT is a white polymer flip-top gas fill with an integral vent and flame arrestor designed for 1.5" hose connections, offering reliable venting and water intrusion resistance in an all-plastic assembly.

This vented straight-neck gas fill is engineered for original equipment and replacement installations where a compact, corrosion-resistant fuel fill is required. It combines a hinged flip-top cap with an internal tank vent and flame arrestor so fuel tanks can breathe while minimizing water entry. The all-polymer construction resists rust and simplifies installation without needing a ground wire.

How does this gas fill keep water out while allowing ventilation?

The Perko 1319DPGWHT uses a continuous venting path paired with a flame-arresting element to let air move in and out of the tank while blocking direct water entry. The flip-top cap and internal geometry reduce splash and rain intrusion, and the integrated arrestor limits vapor ignition risks without metal components.

• Integral tank vent with flame arrestor prevents flash risks while venting
• Flip-top cap minimizes exposure to rain and spray
• Internal channeling supports continuous airflow with water shedding

Will this fit my boat’s fuel hose and how easy is it to install?

This unit is sized for a 1.5" hose connection and is intended for straight-neck installations common on small craft and OEM replacements. The polymer thread and mounting design allow quick fitting, and because it’s plastic, there’s no need for an external ground wire.

• Designed for 1.5" hose hookup — check existing hose ID before ordering
• Threaded straight-neck simplifies placement through deck or bulkhead
• No ground wire required, reducing installation steps

What are the material and durability advantages of the Perko polymer design?

Made entirely from engineered plastic, this gas fill resists corrosion and aging better than many metal counterparts in marine environments. The polymer cap and body maintain function in saltwater exposure and avoid galvanic concerns, while remaining lightweight for easier handling and replacement.

• All-plastic construction prevents rust and metal corrosion
• Lightweight design reduces deck stress and makes handling simpler
• Stable performance in marine environments with minimal maintenance

Does the cap provide safety features for fuel handling?

The Perko 1319DPGWHT includes a flame-arresting element within the vent path to reduce the chance of ignition through the vent while still allowing tank pressure equalization. The hinged flip-top cap keeps the fill closed when not in use, limiting contaminants and splash from entering the fuel system.

• Flame arrestor integrated into venting path
• Hinged flip-top cap secures the opening when idle
• Continuous venting reduces pressure build-up during fueling and operation

Who is this for: The Perko 1319DPGWHT is intended for boat builders, OEM replacement programs and marine owners needing a compact, corrosion-resistant white gas fill for a 1.5" hose connection. It’s a practical choice when you want a straightforward, easy-to-install vented fill that minimizes water intrusion and removes the need for a grounding wire. Confirm hose size and deck cutout compatibility before purchase to ensure a correct fit.
