Give Watson Diesel a ring on 02088793584 -02088793861 they are very helpful..
IIRC There is a large plastic disc on the side of the pump.facing the radiator,unscrew this disc, inside is a bolt with a Allen key head, I think its 4mm and its also very tight so don't use the ball ended type Allen key, use a small mirror to locate it,, please be aware, there is no actual setting for this adjustment, its purely trial and error, but I have done it many times, looking for more power, you will need to turn the bolt ANTI- clockwise, to reduce the amount of fuel, it may take a few goes before you notice a depreciation in performance, or until you achieve what your looking for,

in the haynes it states,The maximum engine speed and transfer pressure settings.together with timing access plugs, ARE sealed by the manufacturers at the factory using locking wire and lead seals.DO not disturb the wire,Also do not attempt the timing procedure unless accurate instrumentation is available,for carrying out pump timing should be left to your main Peugeot dealer.SO IN THE WORDS DONT PLAY WITH IT UNLESS YOU KNOW WHAT YOU ARE DOING...
Totally agree Chris, I don't think the dealer will make any kind of adjustments to the pump though, basically because main dealers do not have a training schedule for pump maintenance and repair, so most technicians don't know what goes on inside the older type diesel pumps, unless the tech, has studied it himself, The earlier suggestion about visiting a diesel specialist is the best option, IMHO Fitzy
So why did you suggest a possible solution 2 days ago? Just asking out of curiosity.
Hi I've had a look at the pump and there is a round disc with a plastic centre and also a very large nut with a pained seal on it would either of these be what I'm looking for ? respects

haynes,says that that is the plastic disc which you do the timing.so i think it should be left to a person that knows about diesel pumps and timing. if you play with it u might muck it up and you will have to pay lots to get it put right.
Thanks for the advice but does anyone know how to ajust it.
