Nozzle Leak Test
WARNING: This page does not describe the selected car, but rather 31 other vehicles, including the 2002 Saturn Vue, 2002 Pontiac Montana, 2002 Pontiac Aztek, 2002 Oldsmobile Silhouette, and 2002 Oldsmobile Bravada. However, it is still accessible from the selected car via links, so may be relevant.
WARNING:
DO NOT place your hands or arms near tip of nozzle when testing nozzles. High pressure atomized fuel spray from a nozzle has sufficient penetrating power to puncture flesh and destroy tissue. This may result in blood poisoning. Always enclose nozzle tip in a receptacle, preferably transparent, in order to contain spray.
NOTE:
Nozzle Leak Test should only be performed on vehicles with high mileage engines that have been overheated or on vehicles that pull heavy loads. False or inaccurate readings can occur if following tests are not performed to this criteria.
- Open shut-off valve at pressure gauge one turn.
- Blow dry nozzle tip.
- Depress lever of manual test stand slowly until gauge reads a pressure of 1400 psi (95 bar). Observe nozzle tip. A drop may form on end of nozzle but should not drop off within a period of 10 seconds.
- Replace nozzle assembly if a drop falls during 10 second period.
