Fix your leaking TDI injector pump's quantity adjuster seals with this Bosch TDI injection pump seal kit. Kit includes seals for all 1996-2003 TDI pumps for the North American market*. This kit includes the top and lower rectangular quantity adjuster seals which are made of Viton. The round green pump head seal in this kit is the less effective Buna rubber (bottom left in picture above), not Viton. If you plan on replacing your pump head seal we highly recommend you purchase the $9.00 Viton pump head o-ring seal kit available separately below. Replacement of the two rectangular quantity adjuster seals requires the Metalnerd MN3001 triangular socket which is also available below. To get an idea of how to replace the quantity adjuster seals without damaging your pump we recommend you read this thread on TDI Club!
Again, if you plan on replacing the round head seal o-ring you should also buy the $9.00 Viton head seal kit shown below.
*The 17mm input shaft seal is not provided in this kit. The Bosch part number for this seal is 1 460 283 311. Again, we do not sell this seal due to the highly technical nature of its replacement. Additionally, there are only three seals in this kit you are likely to use. We do not have information regarding the locations and uses for the other seals in this kit.
