Does fuel air separation systems like Fass Fuel really work? How does it benefit diesel engines?

I have put over 100K on my Duramax diesel with no fuel issues. I change the fuel filter when required and use Standyne fuel additive in every tank. I have been all over our country buying fuel in all kinds of different places and have had no issues with water or contaminated fuel. I personally don't see a need to spend the $$ on a system like the Fass Fuel. Use a good fuel additive and you should be good to go.

Many diesel pickups have factory water separators.

As for air separators, the need depends on the engine/fuel pump.  In my industrial experience, our plant had a portable pump with a Duetz (sp?) engine that we never ran out of fuel.  If the fuel pump air locked, our maintenance crews chewed us out because the system was very hard to bleed.
