TDI Injection Pump Seal Kits

If you want to reseal a leaking TDI injection pump on the car, you have come to the right place for pump seals and DIY information. We sell VW TDI injection pump seal kits and tools to successfully fix a leaking Bosch TDI injection pump. We offer big savings compared to the expense of the diesel injection pump replacement.

Helpful Hint: If your pump is leaking but the car runs fine otherwise we would suggest buying the first three items on the list below to save time and shipping expense. If one seal is leaking, then the other two will start leaking when you fix the first. You might as well get everything in one shot.
