Remove the fuel filter but don't replace it - just leave it open so all the fuel drips out. Here is how: http://www.myturbodiesel.com/1000q/b5/fuel-filter-vw-passat-tdi.htm
Lift the rear seat bottom cushion. There are 3x phillips screws under the seat on a cap. Unscrew the ring cap and lift the fuel pump a little so you can get a suction hose in there.
Suck out ALL the old fuel and discard it. Replace the fuel filter with a new one and replace the fuel pump. Fill the tank all the way with diesel.
A splash of powerservice diesel fuel additive will help add lubrication. Gas is a solvent and can leave behind a varnish. There'll still be about a pint of mixed fuel in there but it's diluted to the point where it's not worth getting it out.
