I've had a thorough look through this forum and all over the web to try to find the location of the fuel filter on my 1.6 156THP. I've also jacked the car up and had a good look round for it. Common opinion on this forum is that there isn't a fuel filter on the petrol RCZ - just a screen on the fuel pump inside the tank.

I bought a fuel filter (Bosch F2161) online. I also emailed the seller and gave them my registration number to check it was correct for my car. Elsewhere on the web there are many sellers selling a fuel filter for the petrol RCZ. This is just one example:-


At the bottom of the page it specifies:-

Fuel Filter for Peugeot RCZ by model and power system

RCZ [03/2010 - Today]

When you click on my model 156HP it brings up a range of filters from different manufacturers but all basically the same design.

So, I'm a bit stumped! I tend to think that there isn't an external fuel filter but I'm confused why there are so many sellers on the web who can sell me one! I have emailed my local Peugeot dealer to ask them for a price to replace the fuel filter and I'll see what they come back with. At least this should give me a definitive reply I guess.

I think there is one variant of RCZ that has external fuel filter. If i am not mistaken, that RCZ was sold in South Africa (and maybe elsewhere) :rolleyes:

Thanks for your reply Nemi. The two Peugeot dealers I emailed haven't replied yet. I have a Fuel Rail Pressure Too Low engine fault and thought it might be due to the fuel filter. It seems likely now that it is the high pressure fuel pump. The last few times I've started the RCZ I've given it a few more revs than I normally would and I don't get the engine fault message. I've also looked at a YouTube post on replacing the HPFP and it's not a job I would want to rush into at this time of year. There is someone on Ebay who reconditions these fuel pumps for less than £150 and his feedback is all very positive. He mentions in the listing that there are lots of grey looking pumps from China but evidence points to them being used pumps which are just sandblasted.

The reconditioner also states that the life of the HPFPs is 60k - 70k - which seems very poor to me. Some people could be replacing them every year or two!

I'm going to wait a bit longer to see if my pump gets any worse.

Cheers. Bruce.

I got the same error (Fuel Rail Pressure Too Low) when my HPFP failed. Most likely you have the same problem. I think you should replace it as soon as possible because you risk getting into limp mode or your RCZ will not start at all. My RCZ broke when i was 200km away from closest garage, had to call towing service :rolleyes:

Just buy a new one, it costs around £300-£400 (maybe even comes with warranty). It takes around an hour to replace it (at independent garage). At Peugeot dealership it may take longer and cost more and i think they are required to update ECU after replacing HPFP as part of standard procedure o_O

And yes, HPFP don't last long, even new ones.

Apparently the new pumps are updated models and should last longer 🤔
