How to replace the diesel filter in a Subaru Impreza.

Model: Subaru Impreza MK 2 - Years 2001-2007
Part: Diesel fuel filter

In this video tutorial, you can see how to replace the diesel filter in a Subaru Impreza: the first step is to lift the bonnet, secure it with the prop rod, and disconnect the negative battery cable and the two connector cables on the right. Using a 12 mm socket, undo the two bolts that connect the pump to the bracket. Remember to disconnect the two connectors from the bracket before removing the pump assembly. Protect the engine with a cloth; to unscrew the diesel filter, you can use a special oil filter wrench. Once the filter is empty, it can be unscrewed from the pump; next, remove the plastic cover from the new filter and lubricate the new O-rings with clean engine oil. The next step is to reassemble everything, so screw the new filter onto the lift pump (tighten by hand, not with the wrench). Final step: operate the lift pump to fill the new filter, (starting the engine with an empty filter could damage the high-pressure pump of the injectors).
