Does anyone know if their mandating on board nitrogen generation/scrubbing or just some system pressurizing the tank with ambient air to prevent vaporization? $200,000 is dirt cheap for any major aircraft systems modification.

The proposed system takes bleed air off of the engine, compresses it through a gas separation membrane, splitting off a good portion of the oxygen content and sends the de-oxygenated air (nitrogen enhanced) into the fuel tank.
