System Leak Testing

WARNING: This page is about a different car, the 1994 Plymouth Voyager, 1994 Plymouth Grand Voyager, 1994 Dodge Grand Caravan, and 1994 Dodge Caravan. However, it is still accessible from the selected car via links, so may be relevant.

If a fuel system leak is suspected, inspect system tubing with a commercially available liquid leak detector. Ensure fuel system is fully pressurized. Apply a generous amount of leak detector fluid to suspected leak area. Monitor area for 3-5 minutes. A steady source of bubbles should appear at leak area. Repair as needed. Proceed to SYSTEM/COMPONENT TESTS - 3.3L CNG article in the ENGINE PERFORMANCE section. If fuel cylinder leak is suspected, cylinder must be replaced.
