Long running process should not be run from udev rules. If udev is run
under systemd it will kill such processes after a timeout (I think it
was 120 secs)

You could use something like udevil or udisks-glue.

If you want to do it via udev/systemd, use SYSTEMD_WANTS

ACTION=="add", SUBSYSTEM=="block", SUBSYSTEMS=="usb", TAG+="systemd",
ENV{SYSTEMD_WANTS}+="foo.service"

Then write a foo.service which does the actual mount.
You can pass additional information to the service if you use a template
