Fuel System Components - Air/Fuel Separator and P-Traps
The Perko Air Fuel (A/F) separator is designed to protect canisters from liquid fuel. Vapors pass through the device to the canister while liquids are returned to the fuel tank.
Perko A/F separators mount using the same "floating bracket" system used on the marine carbon canisters.
Perko P-Traps allow vapor to vent from tank during thermal expansion of fuel.
