I haven't yet got around replacing the faulty stop solenoid on my Lucas pump. I have a 1769 Turbo and I'm unsure what kind of replacement part I need.
I asked my Citroen dealer and they sell those parts for 150 to 210 CHF which is incredibly expensive. Here's what I found on service citroen:

But there are two different part numbers and both aren't helping anyway. On ebay I find plenty of stop solenoids but they all look a tiny bit different and I don't know which one I need.
This one on ebay doesn't look anything like the one currently fitted. This one's more similar but still different. Mine has a green plastic top and a bent metal enclosure. Here's a picture of mine:

Which one should I go for? Needs to ship to Switzerland.
Thanks!
