hi guys.....how easy is it to change a fuel filter on a mk2 2.0TDCI Focus saloon? and where the hell is it located?
Found this post on another Focus website (see below) and it seems quite complicated....should i leave it to the pros?
[b]I did my first ever diesel fuel filter change the other day and learned about all the problems the hard way.
I expect this will apply to the other diesels but not sure.
Firstly the Max does not have a fuel pump in the tank or a manual priming pump to get air out of the system. Old diesels used to have a priming pump but this seems to have been discarded to same costs.
In the box with the filter are a number of plugs. These (I now realise!!) are useful.
Start by having a plug ready and remove the outlet pipe from the filter and immediately fit the plug before any fuel leaks out of the pipe.
Them do the same with the inlet pipe.
Open the filter housing and take out the old filter. Fit new seal. Soak the new filter in some fresh clean diesel in a tin, jar , whatever you have to hand. Top up the filter bowl to a little below the bottom of the threads.
Fit new filter into the filter housing top. Surround the filter bowl with rags and lower the filter & lid into the bowl, screw on and tighten. Some diesel will be forced out and soak into the rag.
Refit the inlet pipe, then the outlet without losing any fuel.
With luck the engine will restart and run OK let it idle until all the air bubble you can see running along the pipe have gone.
Breathe a sign of relief!
If the pipe between the filter and the engine gets too much air in it, the engine will not run.
The way i fixed this was to untangle the pipe from its normal route until I could hold it vertically and the air rose to the top.
Then with a clean pump type oil can filled with clean diesel, I refilled the pipe with diesel until it was full and then fitted the cap. Next i re-routed the pipe correctly and re-connected it to the filter. After several attempts at this, I got all the air out and the engine running reliably but it was a real pig of a job.
Next time I will be much more aware of the issue and take more care.
I have also kept the plugs just in case the next filter pack does not have any in
Hope this might help someone not fall into the traps I did as well help them out of the hole of they do.[/b][color="#FF0000"][/color]
