Hi I’ve got an Audi 80 1.9tdi b4 saloon which I think is the 1z but was after some advice on the injector pump which I believe is a 10 mm one so I need to know if I can put a 11mm pump on and if so do I need any mods for it to fit. Thanks.
Welcome to the forum. You could do a site search or google search for TDI 10mm to 11mm injection pump conversion. You should find a ton of information. The partial answer is yes you can!
