We have a new diameter of vacuum/fuel line added to our program. This new vacuum/fuel line is exactly the same as our BBT ref 0972, but with an inner diameter of 3.2mm.
3.2mm is the perfect size for the return on your T25/T3 Vanagon diesel injectors, even VW recommends 3.5mm in the books. This 3.2mm diameter is the only correct one, as if you look a little further there is also the end cap in the VW books 3.2mm… which means the line should be 3.2mm as well…
Tested and approved by our quality department, this is the line to have for this job!
