This Viton® hose kit replaces the only hoses we have routinely seen degrade on the TDI--the injector return lines. This kit includes a custom end cap that we make out of Viton® as well as all the Viton® hose necessary to retrofit your 1996-2003.5 (non-PD, ALH/1Z/AHU engine codes) 1.9 TDI with B100 resistant hoses.

If you run B100 in your TDI we advise you pop off the plastic engine cover and take a look at these hoses (they are the small hoses that run between the injectors). Degradation usually occurs within 1-3 years of B100 use.

This hose kit will not fit late '03.5 and later Pumpe-Duse (BEW engine code) 1.9 and 2.0L TDI engines.

Also of interest for the TDI is this Bosch injection pump seal kit which can save you thousands if you have a leaky IP.
