Genuine Kugelfisher Membranes and Revision Kits for Peugeot 504
New Membranes & Revision Kits for KF5 and XN2 engines.
Does your 2.0 liter 504 injection engine start consuming more and more gasoline and you can’t figure out why? Then there is a fair chance that the membranes that control the vacuum inside the injection pump got porous. This is especially very likely when the car wasn’t used for some years. Problem for many of us is how to get those damn membranes. I did sell new membranes for many years, but stopped, since complete revision kits from Bosch are appearing again on the market and others have picked this up now. The revision kits do contain the 2 membranes you need, and other small parts as well you likely do not really need…..
The reference number for the revision kit = Bosch 8 492 928 001
Some reliable addresses to get a revision kit are:
- L’aventure Peugeot – see section engine equipment
- TealMaxLion – here you can also buy the special wrench for the suction valves !! see image to the right. You do not need this for replacing the membranes, but if you need to dismantle the pump housing it comes in handy.
- Der Franzose – search for: bosch repair set
- Serie04 – direct link since their search sucks
