I had a few sets of ABF injectors flow tested and cleaned for a project. The injectors came out of different rails and the feed location for the fuel differs on each set. Was this a revision by VW/Bosch? Can I use both styles in one set? I'm asking because the closest flowing injectors are a mix of both styles. I want to make sure im not missing anything, like fuel rail revisions etc. See attached picture for clarity.
