Also what pliers do i need to release pipes from canister fuel filter. Long nose pliers or the type that have a square blocks at the ends and go around the pipe coupling and the square blocks push the tags inward.
Hope that makes sence.

If you have the correct too (the second set you describe) use those, I only used long nose as it was what I had at the time lol
They are free enough that I can use my fingers now

Car had done 106,000 miles when it got wrote off in an accident.

That's the sort of life I'm hoping mine will have!
Chain was done because it had jumped and looking at the service history, I can see why, almost 20k between each oil change certainly will have contributed to that.
Figured better quality of fuel can only help the pump and filter in the long run so for a few pennies extra it's worth putting the higher octane in

Seems strange i seem to of had more pumps than others. Maybe supermarket fuel is fine then. Who knows. As i said i have always run mine on BP since the first pump change at end of 2007, even driven out of my way if on holiday and not local to home to fill up and yet still had problems. Not tryed BP's High Octane which i think is BP Ultimate.
Anyone use this, and can comment on running the 2.2 Direct Z22YH on this ?

Its a very high quality, well mashined pump and instalation is easy as you know, the only additional work is removing fuel inlet from old pump and fixing it to the new one.
It comes with new bolts, new inlet seal (just in case) and high pressure pipe that has different shape due to pump layout.
As the site state this pump does not fail as the old ones due to Etanol issues because it is completelly different design that has no membrane but pistons instead.
It is advised to buy new pressure regulator if origninal is older than 2011. they sell one for around £100, which is about 3rd of OEM price and as I have purchased it it looks like it is in diferent ligue over the OEM one,
So the whole shebang cost around 300£ with DHL delivery costing 17£.
they say it might take 30days to fulfil order but I ordered mine just before christmas and it arrived today (3/01/2020).
I have installed it already and it is a simple job with only trickier part being slightly bending high pressure pipe to fit to pump. No leaks, engine works fine.
The is manual with the pump that explains everything including time that pump need to runn in for first 1000km to work under 2500RPM and then another 1000km when it needs to work bellow 4000RPM.
So far so good.
If anyone is interested in buying my NEW but used for few minutes Continental pump, I am selling it on Ebay for 100£ les than in the shop. It has warranty.

I'm really interested in these new pumps as i have had many problems with my 2.2 Direct. Any additional information would be much appreciated.

Hi everyone.
As i was replying to one of the forum member PM regarding the issue. I decided to post it all here as well in case forum decides to log me off for the third time during typing, loosing an hour of writing :-/
Please regard all this information as common knowledge not professional advise and please correct me if I am wrong somewhere where you guys know I talk bullcrap.
So here it is.
I am not sure how much do you know or researched about the issue, so I will try to explain anyway.
Bear in mind I am not Opel/Vauxhall engineer and all I say is from my own understanding and knowledege I gathered around few issues, although I have engineering degree in relevant field so those things aren't that alien to me.
Why those pumps fail:
Z22YH engine (2.2 Direct Petrol) is designed some very long time ago and with this design comes the pump which is a type using membranes to rise the pressure and cycle fuel to the needs of injection system. Thats why its HP (High Pressure) pump. Together with Pressure Sensor and Fuel Pressure Regulator they supply fuel to injectors according to what ECU is saying it needs at the time.
Now comming back to the design of the pump. Some parts like part of membrane ( I am not exactly sure which part of membrane ), seals and gaskets where designed before EU introduced law that every fuel sold must have at least 5% Ethanol included. Ethanol as an alcohol reacts with materials those parts were made of. It affects a lot of pre 2005 models of various manufacturers depending onengine designs, some less, some extremally strong as Z22YH.
That affects them twofold.
1. Direct detoriation of said parts by alcohol resulting in pores and losing their qulities as sealants, making the pump not providing anough pressure.
2. Ethanol absorbs moisture. Less fuel in fuel tank, more moisture gathers there, water from that moisture is then moved with fuel to fuel supply system and affecting all moving parts and causing corrosion whenever it finds room to settle.
Continental pump is not really the solution. It has exactly the same design as OEM Siemens one and I am not sure if materials were changed, I am not sure when it was introduced. There was some "silent recall" after TV program calling the issue ( parts were changed on cars with warranty, at the scheduled service time, without owners reporting them) but as the model was fairly new I do not know if it was found by Opel/Vauxhall as an issue with ethanol or they thought something else is the culprit.
By now its impossible to do anything with the dealers ( I tried) . No knowledge can be extracted from them at all and its hard to find manufacturers reports or solutions.
That issue affects many parts.
It is recommended to change pump in tandem with regulator. But the dealer's manual easily found on internet states the practice of diagnosing parts one by one. which is not very wise as the issue affected bot parts and soon enough everybody was back at the dealer.
So, when I bought the car about a year ago (2.2 Signum Elite) it was a steal for 1100£ with 45000miles on it, car is basically like new. With tieme it obviously failed me on the way to Poland midway, somewhere in Germany on autobahn, so I had to go 60mph to and back to UK for about 1800miles as car went in to limp mode not allowing going faster than 2500RPM.
I started to find issues and sollutions on this forum. Obviously all sounds very scary as parts are silly expensive (pump would be half the price of the car) and then when you add 70£ per h for the garage you quickly better chuck the car in the cannal.
But I have some skills and I always fix and service my motorbikes, doing absolutelly everything myself. It cannot be much different apart from having means to acces parts of the car working on the street :-/
First I have changed Fuel pressure sensor as it is the cheapest part.
Issue stil persists.
Finally I have decided to buy new Continental HP pump spending 549£ on ebay.
As I was looking to buy regulator which on ebay can cost up to300£ new I found the site of Polish company called F5R. bought their regulator for 100£ and found on their site HP pump they are manufacturing as a replacement for the Z22YH engine. And it only cost 200£.
So I have bought it, thinking what the hell. Tried and sold Continental pump on ebay slightly cheaper than I have paid , as it was on the car just for 5 minutes.
As I am Polish (living in UK for 20 years now) i started to ask questions and have a really great communication with owner and main engineer at F5R, Krzysztof Pawluczuk Mgr
so their pump has no membrane , it has two pistons, all the parts are ethanol proof and the overall design is much more robust and dependable.
Its a direct replacement, meaning that you just unscrew 3 bolts , remove old pump and put the new one in but there must be fuel inlet removed from old one and moved to new one (silly simple operation of unscrewing and screwing on). Also it is advisable to purchase new regulator. They do not insist on theirs but it has to be newer model of the number at least 266 09 engraved, as older ones have different parametres.
I have done all that. I have also replaced sender pump that sits in the tank. It is not essential but I did it anyway as the pump cost 24£ new and the job is easy enough. As my car was sitting motionless for a year or more, there is a lot of moisture and build up in thetank. I am planning to drop the tank and flush it too. Tank sender pump was a bit dirty and connectors corroded but it worked.
I have made sure all possible parts are new, I have changed fuel filter which seats underneeth the car on he fuel line, silly job but needs lifting the car. any garage can do it quite cheap as the part is generic and jobis like 15 minutes.
I have also replaced fuel line that goes from just next to regulator to pump, it is on top of the engine and the job is really simple. I did that as I am not sure those OEM hoses are also ethanol proof so really blowing on cold.
That requiers buying fuel hose, clips and quickconnectors. All are very cheap and available enywhere (amazon, Halfords, e-bay).
I have also put additional fuel filter on that line.
I have asked Krzysztof about it, if its not going to impede fuelflow and he said that as it might collect dirt from fuel that was sitting in the old lines and fuel tank, it lso works as the compensator. In the event of rapid acceleration it helps to avoid creating underpressure or partial vacum in the fuel line betwen regulator and HPpump, as it has some fuel stored in.
There is more to the story as I still had ELi light comming on but no error codes on OBD reader.
I was doing aditional tests as advised by F5R
Two easy ones:
To test if fuel going from tank to HP pump has enough pressure, simple gauge (14£ on amazon) put before pump can show if pressure is hig enough (4bar) wile increassing RPM. if that test fails it is a bit good sign as it means it might be fuel tank sender pump fault and its cheap as chips. It could als be faulty, old or dirty main fuelfilter, or faulty lfuel lines.
Other test was to meassure voltage on sensor at different RPM. I have done this test with camera recording the meeter screen and so far all is well.
There is third test that requiers electronic meeter that can measuere PWM on regulator , it needs %Hz scale and as it is the most meaningful test it is not even performed at the dealer garages. This test shows how ECU works with fuel system.
I have done that and its ok.
I still had occasional ELi light comming on but it stopped now and it might be something else as OBD reader shows no errors.
I was told it might be air bubles int the system as all the jobs I have done disrupt the fuel flow until it stabilises.
Will se later.
They build a lot of injection systems, mainly for trucks, they sell to the whole Europe .
They make a lot of HPpumps for different cars and it migh take taime to get one as the maximum they coud make was about 30 a week. They are absolutelly amazingly helpful and insist on telling them about any issues as, they mght improve design, knowing if anything happening with time of usage.
SO BEAR IN MIND TO TREAT IT AS DEVELOPEMENT SOLUTION, but from their experience, tests and reports there is absoluelly nothing going wrong so far and as the pumps are manufactured for few years already I do not expect it to suddenly fail.
Those cars are very popular in eastern Europe and there is a big market as people do not throw away cars as easily as here in UK and many people try to fix things as much as they can and prefferably by themself.
Here is just going to the garage and paying 60£ an hour to order and replace parts for new.
Now to finish.
I have this all done only month ago. I have no idea whats going to be long term, but at least its not 600£ every year or 100000miles.
F5R are very helpful, during tests I was told to floor the engine as the pump is under their warranty and they would replace it at no costs if it failed. Due to nature of its design this pump needs to be run in. For precustion they say 2500rpm limit for 1000km and 4000rpm limit untill 2000km, but its more of a safety bracket.
I am also adding ethanol susspending fuel add-on, untill atleast I have the tank dropped and flushed.
If you going to have more questions, fire away. I can also help with identifing common parts and procedures if you want to do it yourself.
