Narrative:

A B767-300 arrived with a repeat write up of ''standby airspeed indicator inop''. I replaced the indicator and pressurized the pitot/static system to leak check and verify operation of the indicator. The aircraft departed ZZZ to ZZZ1. After about an hour into the flight; I received word from my lead that the standby airspeed indicator had failed again. My lead was informed by maintenance control; who received an ACARS from the flight crew. Maintenance control states that the flight crew was going to continue to ZZZ1. It was at that time; that I realized that there should have been a static line attached to the indicator; not just a pitot line. The static line was missing at installation; and that the indicator was thought to be bad. I got with my lead and he forwarded the information to ZZZ1 maintenance. Aircraft departed ZZZ1 the next day with no problems.
