Citroen Berlingo 600D 1997 location of diesel fuel filter?

if it is a xud engine it is fitted on front of engine in a black cube shape box with 4 allen head bolts the filter element is inside, there should be a screw at the bottom with a pipe on it to drain any water, the sensor is there as well might be best to change filter and clean out, hope this is some help
