Noise Test

WARNING: This page is about a different car, the 1983 Volkswagen Vanagon, 1983 Volkswagen Rabbit, 1983 Volkswagen Quantum, 1983 Volkswagen Pickup, and 1983 Volkswagen Jetta. However, it is still accessible from the selected car via links, so may be relevant.

Listen to nozzle while it is being tested on special testing gauge (US 1111). Use long, slow strokes of testing pump lever (1-2 strokes per second). If nozzle is working properly, it will "ping" as fuel emerges.
