You need the following

  1. max pressure at zero flow (2.5 bar)
  2. nominal pressure (1 bar) at nominal flow (50l)
  3. max flow at zero pressure (90 l)

Hope this helps!

  Rather than screwing around with the stock fuel pump   why not use a motronic pump with a spill back regulator

  What pressure does the Kugg fuel pump run at?   I don't think that there was anything changing the pressure to the   injection pump

    Hi there,

    I am just done with the painfull exercice of getting my 2-Liter     injection Peugeot 504 Cabriolet to run perfectly.

  1. There is a climate of secrecy about where to find a workshop that can service the (fragile) Kuggelfischer injection pump. I ended up to get it replaced by a fully refurbished pump through a former Peugeot branch owner in Belgium. Ouch, for the budget!
  2. Be very careful with second hand replacement parts. In particular, for the electric fuel pump (located in the back near the fuel tank) I experienced the same as Graham back 6 months ago (http://www.vectorbd.com/peugeot/archive/504/2005/Sep/0026.html). Interestingly enough, with the same guy (Kurt Orbie in Belgium), I tried 2 different of his spare units. There were both leaking like hell. Even the guy did not admit something was wrong (a working pump not only runs electrially, it should not leak and bring up enough pressure...) and that his parts were just crap. Worrying is that he was probably going to sell them to someone else... :-( So I won't comment any further on how reliable this source for used parts is...
  3. After all, an electric pump is just a pump with basic specifications (max pressure at zero flow, nominal pressure at nominal flow and max flow at zero pressure). I have tried several equivalents and it seems I found one which appear to be OK to complement or even replace an old aging original pump. Good news, it sells for less than 100 Euros in a good auto-part shop. I will send full technical info to those who are interested.

    Other than that, I am so happy to finally enjoy my 504 with no more     hot restart problem (no more 30 minutes wait during a club rally...)

    Cheers!
