I am going to replace the fuel filter on my 2006 Ford focus sport 1.8 TDCI. It is rather easy to access, no need to get underneath the motor e.t.c.  it is at the top of the engine on the left side near the battery and just below the rocker cover

My car is diesel.  do any relays or fuses need to be disconnected before replacing the fuel filter ?   do I just disconnect the sensor to the filter and remove the fuel supplies from the casing ?

 

thanks

No (relays / fuses), Yes (unplug sensor).

The difficulty is getting all the air out of the system after.

I have just done the job (Today!), I fitted a non-return valve, & used a priming bulb.

It started, stopped, I re-primed it, started (normal short cranking time), and ran ok. Then removed priming kit, niot allowing any air in, and it started again ok.

I am planning to do a little guide with photos, as it causes lots of problems on this car. But it will be a week or two to put it together.

(If it fails to start, do not be tempted to touch the high pressure pipes, the problem will be on the inlet side of the pump.)

Are you suggesting that once replacing the fuel filter that the fuel system has to be bled afterward ?    what is the process of beeding it ?

 

thanks !

That is what my guide will be about.

Some people fill the filter canister, then back fill the filter outlet pipes using a syringe or similar. This is messy, and there is a small but very serious risk of getting contamination into the (very expensive) diesel pump like this.

The Ford way uses a special hand pump on the filter inlet to ram fuel into the system. If you can wait a week or two, I can give details with photos of my procedure.

I'm not a mechanic, I just had a brand new fuel filter in my car's boot that has been there for a while, I thought it looked fairly easy to replace the fuel filter but didn't realize that you may have to bleed the fuel system afterwards.  is this difficult to do, what about for an experienced mechanic ?

It should be a pretty routine job for a mechanic with relevant experience and the right equipment.

I am a fairly experienced diy'er. 4 years ago, when I did this job last, following the Haynes procedure, it took me two days of hard, stressful work to get the car re-started. This time, with experience & equipment, it took about 2 minutes to restart.

 

A large syringe or primer pump to fill the lines & filter bowl and a jump/boost pack to keep the beggar turning over until it coughs and fartz back into life 😊
