Your problem is almost certainly a failed lift pump, dealt with exactly this problem just the other day, the car will have been fine until the circuit seal was broken.
ERR5057 is the part number, you will also need 2 brass pipe olives to go with it.
We've never had a problem with Brittpart filters, apart from FL TD4 ones that were too long!

Fitted the new filter after filling it up with diesel and then came to the bit where you have to prime it using the litlle handle. Played about with that for ages but it didnt seem to bleed at all.

I know you have got it going but for the future, the lift pump works on a cam lobe, if the pump is sitting on the cam then the manual lever will not work as the pump stroke has already been taken. You need to rotate the cam about 180°, so a flick on the starter will take it off cam then it should work. Also, the 300tdi is self bleeding, best thing is to fill the new filter with fuel, put diesel on BOTH sides of the o-ring and then fit it. Turn the engine on and DON'T touch the accelerator. It might run rough for a few beats and that should be it.

I have also seen the manual lift pump levers fail because the edge of the lever works on a lobe inside the pump, due to the pressed metal construction of the cheaper ones this can cut the lobe and it fails as it no longer moves the lobe.

sounds like air in the fuel to me. First time I changed my fuel filter it created lots of running problems. Spent hours trying to resolve poor firing and felt the fuel pump was not effective for priming. I popped round to see an uncle who is pretty smart with diesels and he advised me to undo one of the nuts (a quarter turn or thereabouts) on one of the injectors. Then just to turn the engine overand the troublesome air in the fuel will come out. You will also get a fine spray of diesel. Tightenthe nut back up and hey presto should run like a dream. This method has worked everytime for me and I always undo one of the nuts a little just to make sure. A few seconds should be plenty. Good luck anyhow.

Yes, the olives are compressed onto the fuel pump inlet and outlet pipes.
