Choose a finish that fits your boat. Perko offers chrome plated, black, and bare bronze options for fills and caps. Vented fills let fuel tanks breathe safely, and inlet check valves keep flow moving one direction. Replacement caps with chains and inserts let you renew a worn fill without swapping the whole unit. With most parts made under Perko's own roof, fit and quality stay consistent.
Many Perko fills and vents are built for 1-1/2 inch hose in straight or angled neck styles. Always confirm your hose inside diameter before ordering.
Perko offers chrome plated, black, and bare bronze finishes across fills, caps, and adapters so you can match your existing deck hardware.
Yes. Perko sells replacement caps with chains and inserts, so you can renew a worn cap without replacing the entire fill assembly.
A vented fuel fill lets the tank breathe as it fills and draws down, which is important for safe and proper fuel system operation.
