Injection Nozzles: Notes
WARNING: This page is about a different car, the 1984 Volkswagen Rabbit, 1984 Volkswagen Quantum, and 1984 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
It is not necessary to perform spray pattern test on injectors. Tests indicate that neither engine performance nor burnt glow plugs are related to spray pattern.
CAUTION:
Keep clear of fuel spray when testing injectors as diesel fuel will penetrate exposed skin at operating pressures.
