Like inverted loops, these devices use gravity, along with complex water channels, to prevent water from entering the tank vent system.
Perko P-Traps are integrated with a deflector vent and offer an effective, space-saving method of keeping liquid water out of carbon canisters.
Allows vapor to vent from tank during thermal expansion of fuel, and while refueling
Allows outside air into the tank during thermal contraction of fuel, or when fuel volume decrease during engine running
Protects carbon canisters and engine from water
Deflector-style vent opening reduces the amount of water that can enter the unit
Internal P-trap and check valve prevent water from passing through the unit and into the fuel
Available with straight or 90 swivel hose connection
Available with black or white polymer splah guard
