I see someone else has mentioned the Haynes manual from the UK. Mine
cost about $35 including airmail postage. Took about 3 weeks; I faxed
the order with my credit card number. (I think the phone numbers ore on
the website <http://www.vectorbd.com/peugeot>, if not email me and I'll
look it up.)
I've found that the 504 Deisel Haynes manual (US) has been a helpful
supplement (even though I've got a 505 gas).
Factory manuals can be obtained from the sources that can order from
Peugeot (perhaps Bailie or French Connection will comment here?). They
are rather spendy. I've got the 505 Electrical manual and it is
wonderfully laid out and easy to use. I don't know about the other
factory manuals though.
I use a Volvo manual for the fuel injection, Bosh K on my Peugeot (my
volvos are D & L versions!).
Good luck,
