So this is write up of how I changed my fuel filter on my 2009 Skoda Superb Mk2 2.0TDI CR 170
1). Things you need:
A replacement filter.
A Can of new diesel fuel.
Torq drivers T20
A flat Blade Screw Driver.
Suction hose, to a bucket or similar.
Open the bonnet, the fuel filter is located at the bottom left of the picture.
2). It has 5 screws to remove.
3). They are of the Torqs type.
4). The screws should not be tight, so a set like this should be fine for the work.
5). T20 is the correct size.
6). Spray them with penetration fluid.
7). Undo the first one.
8). undo the second one.
9). Undo the third one.
10). undo the forth one
11). Then I came across one that had seized in and needed a better tool for the job. undo the fifth one.
12). Using a flat bladed screw driver, place the blade in the lifting slot and open slightly.
13). Release the hoses so there is sufficient movement.
14). Remove the top.
15). using the screw driver remove the filter.
16). This is it removed. Place in a plastic bag or similar and then dispose of.
17). Look inside.
18). The old fuel and bits need to be sucked out, along with any water that may be in there.
19). Using a suction hose suck the fuel and bits out into a bucket.
20). Get new filter ready.
21). Remove the old o-ring from the head.
22). Gently pull it off and out the grove.
23). And remove.
24). Clean the head up with paper towel.
25). Fit new O-ring – which will have come with the new filter.
26). Insert filter with the top upwards. The top has the hole in it.
27). Put paper towel around the filter hosing body.
28). Ge the clean new diesel fuel ready.
29). Fill the housing with fresh diesel fuel.
30). Gently place the head one the housing, there will be fuel spillage hence the paper towelling. Put first screw in and finger tighten.
31) Put all the screw in finger tight and then tighten to 7Nm. It does not need to be overly tight.
32). Put the hose back in position.
33). Clean any spilled fuel.
34). Start the engine. It may cut out. If so restart it again to bleed and air out.
35). Done – pack away.
