Narrative:

An EICAS message; hydraulic 1 qty lo indication during cruise alerted us to the hydraulic 1 pump leak engine 1. We monitored the indications and advised dispatch and maintenance via ACARS. The hydraulic system 1 quantity dropped notably for the remainder of the fight. Looking thru the logbook revealed a recent history regarding the hydraulic pump and frequent servicing. A hydraulic fitting had been replaced the day before. After consideration the first officer (first officer) and I decided to continue on to destination. We advised ATC of the problem and asked for priority handling and short cuts to the airport. We were taken off the arrival in order to get priority handling and short cuts. With the hydraulic 1 system qty extremely low and hydraulic system 1 failure imminent; we wanted to get to the airport as soon as possible; slow the aircraft down and get the gear down early to avoid any landing gear extension issues. We followed ATC instructions; heading; altitude etc. To an ILS approach and landing. Ground crews followed us to the gate without incident. Hydraulic system 1 leak; could have resulted in a hydraulic system 1 failure; and subsequent manual gear extension procedures.
