- Install injector in tester. See Fig 1 . Bleed air from injector. Pump lever with short, quick strokes (4-6 per second). Spray jet should be compact and stop abruptly. Injector must not drip.
CAUTION:
Do not expose hands to injector spray during testing, as working pressure will cause fuel oil to penetrate the skin.
