Do you have to crank and crank your TDI to get it started? Do you have a puddle of diesel on the floor of your garage? If so, you need our seal kit to get your old car back. Contained in this kit is a pair of o-ring seals in Viton material for the TDI injection pump's cast iron "head". The o-ring goes between the aluminum pump body and the cast iron head and is the fix for a pump that has lost it's prime. The Viton seal we sell is superior to the Buna o-ring supplied by Bosch. In addition to the two seals, the kit also comes with one 6mm x 55mm Allen stop screw and eight plastic dust caps used as dust seals for the four injectors and four output delivery valves on the injector pump. The 55mm Allen stop screw is used to keep you from pulling the pump head out too far during the seal swap. We now provide two o-ring seals in case you damage one, a real convenience!

here for the replacement procedure. This o-ring kit fits all 1996-2003 TDI injection pumps regardless of engine code. This seal also fits many other Bosch pumps with both electronic and mechanical throttling however we do not offer support for non-TDI VW/Audi pumps.

Thank You Diesel Geek January 20, 2017
Reviewer: Justin from Nebraska  
Found the head leaking on my Jetta called a few diesel shops got quotes from 800 to 1100 to reseal the pump. Did a google search and found this kit. Very detailed instructions and high quality parts. Thank you diesel geek you saved me a ton of money.

Perfect Kit September 22, 2016
Reviewer: tim from PA  
Had noticed a diesel smell, saw the leak, and was able to narrow it down to the pump head using DieselGeek's videos.

Kit instructions are extremely detailed, even down to the color of the various screws you will be taking out in order.

The extra details like caps to protect the injectors and fuel pump are appreciated.

Ordered at midnight, shipped at 9am, delivered 2 days later. Even got a rapid personal response to a question about replacing all the seals or just the pump head.

Pump Fixed!!! November 21, 2014
Reviewer: Robert Stickles from Goldsboro, NC United States  
I can't say this enough.  They have thought of everything.  I changed my pump seal with this kit and I was in a hurry.  Big mistake.  I pinched the O-ring and couldn't get the pump to prime.  Thanks to Dieselgeek I had another O-ring.  This kit is really worth your hard earned money.  Thanks for taking the time to remove the guess work from trying to find the right parts!
