Thread: 2.2l fuel filter change

I believe the 2.2l has a pump in the tank compared to the 2.4l which didn't. Does this mean that all you need to do is remove the old filter and fit the new one (with or without filling it with diesel) and turn the accessories on until it is ready to go and then crank the engine over?

Sorry for my lack of technical terms.. I've learnt everything I know from aulro

Thanks

Fill it to make sure it's primed, it's pretty basic unless you plan to crack a line open after the filter with the pump running to bleed out the air.

On older diesels pre filling was often the norm but I would not be pre filling common rail filters prior to fitting. These injectors are very sensitive to contamination failures. Even what you might think is clean diesel can be a problem. Of course it is often "luck of the draw" as to whether you have a issue...

So to clarify, is the pump in the tank a low pressure higher flow lift pump?
Does this provide flow before the engine is started?

When the fuel filter is replaced, there will be an air lock in the lines. How does the fuel system (or vehicle mechanic) handle an air lock?

The parts of the service manual I've looked at for this process are a bit basic. There is also reference to a special tool to provide suction to the fuel lines prior to the high pressure pump on the engine.

When I changed the fuel filter on my 2012 2.2 130 I just swapped the filters over and the fuel pump did the priming, I didn't start the engine for a minute to ensure that all the air has been removed.


And then I kept the revs up for another minute once the engine has started.

Yes as already mentioned, on a common rail diesel you should avoid filling the filter.

*Yes the 2.2lt has a lift pump in the fuel tank.
*ignition on, about 20 secs of so (it will then turn off).
*You can do the above a couple of times (some vehicles require about 5 times to ensure all air has been purged back to the tank).

.

Like all common rail diesels, the fuel system is a loop back to tank, there will be no air lock, once primed as per my last post.

Daz,
On the 2.4 do you pressurise the fuel tank following replacement of filter to force fuel to the first stage pump?
or do you put a priming pump in line?

I use a pump that plugs in line where the filter is, u can do it at the engine too, its nothing clever, a squeezy pump with fittings at each end.
