Looking at servicebox the peugeot part numbers are 4007ZF,4007ZE, 4007ZG, 4007ZH, 4007ZJ, 4007ZP, 4007ZN, 4007ZK,4007ZL, 4007GH depending on your RPO number..to me they all look identical but as i have never had a 407 i will leave it to someone who knows more about the 407s

This is the problem with searching by part number the numbers terry quote are PEUGEOT part numbers these are NOT stamped into the parts.

The numbers the OP quoted are the MANUFACTURERS part numbers IE HPi is the manufacturer.

In reality it probably makes no difference what the number is on it
assume nothing check everything twice !!

I recently had the same problem with a 307.

The part number in ServiceBox has format NNNN.NN and this is never marked on the actual part.

Each part has a reference number which is a long number that starts with a 9 and this is usually on a sticker on the part.

I would dearly like to know more about the relationship between part numbers and reference numbers.

The pump itself will have different variations, for example a SW will need more assistance to compensate for the weight while a 2.2 HDi will need to a have a sportier feel, so less assistance.

iirc, the coupe's pump has the least assistance and switches off at lower speeds.

Then after all of that, you'll have revisions, so potential hardware flaws in the design will be fixed.

On top of all of that... there will be an underlying control mechanism which requires it's own code and each software revision will also have a new part number.

Usually you should be fine with replacing a pump from one to another, as long as the plugs, connections etc are the same.

407's had 3 major revisions, upto ~2007 and then from 2009. So depending where your car fits in, it's best to buy used parts within those years.
