Was kind of dumb from me referring a diesel injector, gasoline ones are

Other thing you may consider are those printing markers used in
production of cables, tubes , metallic rods (and almost everything else)
used for side marking of lengths, dates, part number, etc. Some are
inkjet type, they have larger and fewer dots, could be capable of more
viscous liquids.

Proper inks are difficult to source. But pump+tubes+single-dot-head is
too complex.
