Fuel Filter Replacement; Water Separating Pre-Filter Replacement - Volvo EPA2007 D13F Reference Manual

Fuel Filter Replacement

Note: Because of ice buildup or fuel waxing which can clog fuel filters, it may be
necessary during extremely cold weather to reduce the time or mileage interval
between fuel filter changes.
Be careful to prevent foreign matter of any kind from entering the filters during
service.
Install new fuel filters dry.

Water Separating Pre-Filter Replacement

To replace the water separating pre-filter:
1 Disconnect the electrical cable.
2 Make sure the filter casing is thoroughly cleaned. If not already done, wash the
area around the filter mounting adapter with a suitable solvent and blow dry with
compressed air.
3 With a suitable container in place to collect spillage, open the fitting and drain
the filter.
4 Unscrew and remove the water cup.
5 Using a filter wrench, remove the filter from the mounting bracket and discard
it safely.
6 Apply a thin film of clean engine oil to the sealing gasket of the new filter.
7 Screw the new dry filter in place and tighten an additional 3/4 to 1 turn by hand
after the gasket contacts the base.
8 Screw the water cup into the filter casing.
Note: There is a new-style pre-filter with a stepped-down diameter at the bottom
of the filter. The earlier-style filter has straight sides with a larger bottom diameter
which requires an adapter to attach the fuel/water separator bowl to the filter. When
replacing the previous straight-sided filter with the current stepped-down version,
the adapter is not used. However, do not discard the adapter as it can be used
should inventory of the earlier-style filter still be available.
9 If necessary, replace the full-flow main filter. See the following instructions.
10 Connect the electrical cable.
11 Start the engine and run at idle for five minutes to fill the filter with fuel.
12 Check for leaks.
