Perko Vented Fuel Fill with Angled Neck for 1-1/2" Hose — Black Polymer, Gas-Marked Cap & Flame Arrestor

Perko 0542DPGBLK is a black polymer, vented fuel fill with an angled 1-1/2" hose connection, designed for safe, compact marine fuel fills.

This vented fill combines a compact angled neck with an integral vent, flame arrestor and anti-surge valve for marine fuel tank access. Built from black polymer for corrosion resistance, the assembly fits a 1-1/2" hose and accepts a 5/8" vent hose, mounting to a 3-5/8" outside diameter flange and requiring a 2-1/8" mounting hole. The cap is gas-marked, keyed for the included deck plate key, and secured with an attached polymer strap for easy handling on deck.

What hose sizes and openings does this vented fill fit?

The fill is engineered for a primary hose of 1-1/2" and a vent hose of 5/8" to match common marine fuel installations. It requires a 2-1/8" diameter mounting hole and sits on a flange with a 3-5/8" outer diameter for secure deck attachment.

• Primary hose I.D.: 1-1/2"
• Vent hose I.D.: 5/8"
• Mounting hole diameter: 2-1/8"
• Flange outside diameter: 3-5/8"

How does the venting and safety features work?

The unit integrates a tank vent with a flame arrestor and an anti-surge valve to help control vapor flow and resist flame propagation. These passive components help manage pressure and reduce the risk associated with fuel vapors without changing regular fueling procedures.

• Integral tank vent for controlled airflow
• Flame arrestor to help reduce ignition risk
• Anti-surge valve to limit backflow and splashing
• Gas-marked cap for clear fuel identification

What are the materials, mounting, and handling details?

Constructed entirely from black polymer, the fill and cap resist corrosion and weathering in marine environments. A polymer strap keeps the cap attached to the body to prevent loss, and the cap is keyed to the deck plate for secure closure. Installation uses #8 screws into the flange.

• Black polymer cap and body for corrosion resistance
• Included black polymer strap prevents cap loss
• Deck plate key fits the gas-marked cap
• Mounts with #8 screws for reliable fastening
