If air makes it to the injectors, the engine shuts down and you have to bleed it from the high pressure pump. There is air in the tank because the tank is a vented system, but the pickup is on the bottom, so nothing but liquid fuel gets sucked up. I serviced small sailboat diesels for years and never had a fuel foaming problem, never herd of it. The only air problems I encountered was from cracked fuel hoses and faulty fittings sucking air between the tank and the lift pump. I'm going to have to call BS on that one.
