Fuel Pump 996 GT3 2004

Recommended Posts

Hoping there is someone here who can help with me identifying the fuel pump part number for my 996 GT3 Model year 2004 (was delivered June 2003). The item in the parts list diagram is 4. The four parts listed are

4    996.620.103.90

(4) 996.620.057.90

(4) 996.620.057.91

(4) 996.620.057.92

In the remark column the last three are described as '04-'. I made some initial enquires as I assumed that the parts are listed as they are 'upgraded', so I should order the part with 92 at the end. However I was told this is not the part for my car and that I should order the first part in the list. I am now confused as the first part in the listing does not say 04- in the remarks column, and my car is an 04 car. Sorry for the verbal diarrhoea.


Any help appreciated,


VIN Number WP0ZZZ99Z4S690311

 I have attached what I think is the correct page from parts cat.

The difference can be something so simple as a part supersession.  They don't tell you what changed -- it would be great if they did; it could be a supplier change, an actual upgrade or change of some aspect of the part itself, etc.


The safest thing to do is always to order OE parts for your car using your VIN like you did above and don't assume.

Update Loren.


Firstly I must appologise for incorrect info in my first request. I had assumed that my car was 04 model year, however on checking my authenticity certificate is clearly states 2003, sorry.


I have just received the pump and there have some significant changes to the pipe layout. it looks as if the venturi/jet pump is now powered by the return fuel flow. In fact the pipework is considerably simpler. Also the non-return valve on the fuel flow pipe to the engine has been removed.
