Perko 0542DPGBLK Vented Fuel Fill, Angled Neck, Black Polymer, for 1-1/2 Inch Hose

The Perko 0542DPGBLK is a vented fuel fill built for boats using 1-1/2 inch fuel fill hose. It combines the deck fill cap, body, and tank vent into a single angled-neck fitting, so the vent path is integrated directly into the fill rather than requiring a separate vent fitting. The vent incorporates a flame arrestor and an anti-surge valve, which helps control fuel vapor and reduce splash-back through the vent line during fueling and while underway. The cap and body are molded from black plastic, and the fill comes with a matching black plastic strap and a deck plate key for opening and closing the cap.

This fill is sized for 1-1/2 inch fuel fill hose and 5/8 inch vent hose, with a flange outer diameter of 3-5/8 inches, a mounting hole diameter of 2-1/8 inches, and number 8 mounting screws. It installs through a deck or hull cutout matching those dimensions. In locations where splashed water may reach the fill, Perko offers a separate heightening ring accessory (in split or non-split versions) that raises the fill opening an additional 3/8 inch above the deck surface to reduce the chance of water entering through the vent; this ring is a distinct accessory item, not part of the 0542DPGBLK fill itself, and it will not protect against a fully submerged or flooded cap.
