Procedure for Bleeding Diesel Filter

Model: Vauxhall Astra Astra F - Years 1991-1998
Part: Diesel fuel filter

Sometimes it may be sufficient to bleed the diesel filter rather than replace it: this procedure is suitable when water is present in the fuel due to condensation forming in the distributor tanks. The diesel filter is located at the rear of the engine, mounted to the vehicle's chassis: to bleed it, simply loosen the bleed screw (located at the rear left corner) and then open the lower drain plug, placing a container to collect the bleed liquid (this will certainly be a mixture of water and diesel that must be disposed of properly).
At the end of the operation, tighten the drain plug and the bleed screw.
