Yet another possible HPFP failure

Hello TDI club,
Long time lurker here but thought you guys would possibly provide the best advice. I do apologise given there's a million threads on the HPFP but many of you are from across the pond which seems to affect the situation sightly.
The vehicle in question is the following:
Vehicle: Volkswagen Golf MK6
Engine: 2.0 TDI 140 CBAA
Year: 2010
Mileage: 120k
Location: United Kingdom
Scenario:
I bought this car on the 14th of April, and misfuelled it two weeks later. I put in 17 litres of petrol over half a tank of diesel. I noticed my mistake the moment I pulled out the fuel nozzle and smelt the fuel. What I did not know however is the extent of damage it can cause to a CR engine. I proceeded to top the rest of the tank up with another 12 litres or so of diesel to try and dilute the petrol and drive away (big mistake I know). I drove it 5 miles that day, and took it to a mechanic to get it drained the next day after reading all the horror stories online and on here.
The fuel tank was drained I filled up half a tank of BP Ultimate Diesel, driving it the day after thinking everything was all good to go, until about 15-20 miles into my journey the dreaded glowplug light started flashing. The car started losing power on the motorway and I also noticed the temperature of the engine going down as expected. I got to work limping the car on the roads and a colleague of mine put his OBD2 scanner in and noted the following code: P0087 - Low Fuel Rail Pressure. I drove the car back the same 30 mile journey back the same day and the car stalled just as I got to my house.
The next day I took it back to another mechanic who put his OBD2 scanner in and noted the following code too: P0192 - Low Rail Pressure Circuit Low Input. He proceeded to let me know that it would cost £500 just in labour for a fuel system flush and HPFP replacement to which I kindly replied to p*ss off.
The car has been in my driveway to date, and I'm planning on repairing it this week. I opened the fuel filter housing and noticed the following:

Quite a few little metal 'shavings' are visible, and are magnetic, so its definitely metal.
I removed the fuel regulating valve to look for evidence of swarf and it is clearer than my goals in life, as can be seen

The regulating valve itself also seems to be relatively clear from shavings.

I bought a second hand fuel pump off ebay, along with a timing belt kit and all the tools required to replace the HPFP, timing belt and waterpump.
My question is, do you guys think the HPFP even has failed? The whining noise that occurred and clicking when idle and when pressing the accelerator seems to be indicating high pressure fuel pump failure. Having looked at other threads on this forum though had me believing the car shouldnt even start (mine will albeit cranking a fair amount) and the pump should be showing more evidence of contamination? I can still smell petrol in the HPFP and in the fuel tank after having removed the in tank fuel pump. I'll be removing the pump piston that has the roller attached to it to inspect the roller and the cam thats on the drive shaft.
I'll be cleaning out the fuel tank and all the fuel lines, fuel rail etc, and replacing the HPFP. Is there even a need to replace the injectors if the pump hasn't failed catastrophically? I'm still contemplating sending the injectors off for ultrasonic cleaning but I'm struggling to find specialists around the London area that service diesel injectors. Can I expect the in-tank fuel pump to be damaged, and the electric fuel pump? I appreciate you guys will only be able to provide me advice based upon the information I have provided, and visiting a specialist would be better but I can't afford it at this moment. I am an engineer in training at the moment so fixing it by myself shouldnt be a great issue with the wealth of knowledge available on the internet and my Haynes Manual.
Thank you for responses

Ouch! If I were you, upgrade to cp3 pump. Its the best investment I ever made. But of course clean up the whole fuel system. Not sure about injectors, Best if others chime in.

Yes^^^^^ What he said. Just get it done. Email Andrew and he will get you set up. No sense in replacing with the substandard stock set up.

I'd say the hpfp is eating itself. You might have caught it before the injectors got ruined. Good luck!

Bit late responding but ive been working on the vehicle for the past few days. Evidence of HPFP is there but I took apart the old pump and the roller and cam on the pump seemed to be in OK condition. I'll try to upload a picture of the pump later. I'm suspecting the lift pump could be on the way out.

Sounds like you have a plan.

My bad, I'm not used to forums like this, how do I resize them? I just plugged in pictures from an image hosting site

Hydralic in the CP4 sucks! Get CP3 and call it a day and wont have to worry about it ever again. It even give me nice MPG gains and a tad more power and smoother acceleration.

Think about it... CP4 have one tiny wimpy piston, CP3 have 3 pistons.

Question, I have read many of the forums about solving the p0087 and none of them have been finished with a conclusion. I had the same misfuel issue. When it happened the car just died and wouldn't start....no codes present at that time. Replaced HPFP, injectors, filter, timing belt, water pump, and thoroughly cleaned the lines. This code is now randomly popping up. I have a hard time believing it has anything to do with the lift pump. I double checked the rail and lines for leaks and have none. The engine runs like a top when the light isn't on. This pump was a massive failure by the way....so much metal it clogged all injectors and covered the bottom of the filter reservoir with metal. 2012-13 VW 2.0 TDI Passat

I say 2012-13 because the title says 2012 but I ordered the wrong injectors the first time around. It had 2013 fuel rail setup with these injectors

No kidding and try to post pics that are in focus.

I had that code pop up, turns out the fuel return line and the fuel supply line were on the wrong way round on the lift pump, this solved my issue after doing the whole repair
