Mazda BT-50 B-Series Engine Vacuum Pump – OEM WL51-18-G00A

Overview

A replacement engine vacuum pump for Mazda BT-50 and B-series diesels, referenced to OE number WL51-18-G00A. The manufacturer lists it for Mazda BT-50 from 2008 and B2200, B2500, B2600 and B2900 models from 2002. On diesel engines the vacuum pump supplies the vacuum that assists the brake booster, and when it wears out the first symptom is usually a brake pedal that feels hard or unassisted, along with an oil leak from the pump body. Because these models remain widely used as work vehicles in New Zealand, this is a safety-relevant repair part with steady demand.
