Fuel Line & Fitting Leak Test

WARNING: This page is about a different car, the 1995 Plymouth Voyager, 1995 Plymouth Grand Voyager, 1995 Dodge Grand Caravan, and 1995 Dodge Caravan. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION: Fuel line and fitting leak test MUST be performed any time fuel line or fitting is serviced.

With fuel pressure on fuel line and fittings, apply a generous amount of liquid leak detector on fuel line and fitting. Watch for steady flow of bubbles at fuel line and fitting to indicate a leak. Repair fuel line or fitting as necessary if leak exists.
