Fuel tank is fitted with an internal capacity limiting tank which provides an air chamber within tank to ensure space for fuel expansion when tank is completely full. Limiting tank is open at bottom and has a control bleed at top which prevents it from being completely filled when main tank is filled. Main fuel tank is vented by a line extending to a low point in the separation tank.
