Air/Fuel Separator
Overview
These devices are a mini surge tank and can also be used instead of floated tank vent valves mounted on the tank. They allow vapors to pass through to the canister and accumulate small amounts of fuel that will drain back to the tank, thus protecting the canister. Air/Fuel separators are 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 Perko-Delphi carbon canisters.
- A 0588 series TVV is mounted inside each Perko A/F separator giving it rollover protection, overpressure relief and the restriction needed to aid in automatic pump shutoff.
- Heat shields are available for use in engine compartment installations.
- Properly installed, A/F separators can replace tank vent valves eliminating the need to provide access to distant parts of the fuel tank.

Air/Fuel Separator Access Issues
Perko’s Air/Fuel Separator helps solve difficult access problems. Running internal vent lines (in either plastic or aluminum tanks) and replacing the tank vent valves with an Air/fuel separator eliminates the need to provide access to distant corners of the tank.
Air/Fuel Separator Positioning
Perko’s Air/Fuel separator must be positioned horizontally above the highest level that fuel in the tank can reach during full tilt or storage. The further away from the port/starboard centerline of the tank that the Air fuel separator is located, the higher it must be positioned above the tank.
