Default Bleeding Fuel System

Have just changed the fuel filter on my 207 SHDi 1.4 Diesel (2008).

Have been pressing the priming bulb for what seems like hours, but can't get the air out and the fuel in !!
Have got various bits of kit so could either :
1. Suck fuel through the system to get rid of the air.
2. Use a syringe-type thing to pump fuel manually into the system to get rid of the air.

In hindsight, I should probably have filled the new filter with diesel before putting it back, but I didn't. I guess that's a third option.

So .......... what's the best "plan B" and can anyone confirm which is the inlet and outlet sides of the filter - I assume the connector on the back partly under the air filter housing is the inlet from the tank, and the front connector is the outlet to the high-pressure pump and rail, but it's difficult to see down there.

All advice gratefully received.

I doubt you can get the pipes wrong just remove the inlet pipe from the filter then prime the bulb till you get fuel if you dont get fuel then it may be a faulty primer.

if your priming bulb does not get hard then you have an air leak, check the fuel lines under the air filter housing as it is common to get damaged there

reliable406 & trustme - thanks for that.
I guess it could be a problem with the fuel lines, but everything was 100% OK before I did the filter so no reasons to suspect any damage unless I just did it !!
Do you know which way fuel flows through the filter (is back pipe inlet and front outlet or other way round) and is the priming bulb before or after the filter - am I sucking fuel through the filter when I squeeze it ?

Haynes isn't much use when it comes to understanding how the low-pressure side of the system works.

I just removed the filter, filled it up with diesel, and put it back but still the same problem. 5 minutes squeezing the bulb, and no appreciable difference - still soft !! (Please .........No jokes about asking the wife to try.)

check the pipes are connect properly on filter and if its a sealed filer then that means you moved the pipes that could have just finished off a split

Thanks. Yes - It is a sealed unit and the pipes are properly connected and pushed on till the collar "locks" around the lip.
before I admit defeat and call the garage, I would like to suck fuel through the filter just to rule out any air before that. I have a vacuum pump so is the "outlet" of the filter at the front or the back please.
Thanks again.
Cheers,
David.

Should the transparent pipe (with the green clip) be full of fuel ? - as far as I can see, it's not.

trustme - thanks. Please don't think I'm not grateful for your knowledge and experience, but before I start a fairly major dismantling job, I would just like to try and rule out any other possibilities (e.g. faulty one-way valve in the priming bulb.)
I have a suction pump - is there a point at the end of the low-pressure circuit where I could connect it to see if fuel, air, or both, get pulled through.
Is that transparent pipe a suitable place, and if so, how do you disconnect those clips - again - Haynes is as much use as a chocolate teapot !

you wont really be able to do as you are suggesting main reason is the way its all connected you wont get a good connection anywhere !

Best place to suck fuel through would be at pump inlet but its buried down the back of the engine !

Disconnect the inlet at the filter housing and apply suction there it should pull fuel from the tank this should then allow the primer to prime.
