Operate Selector Valve (Dual Tank System)

WARNING: This page is about a different car, the 1995 Ford RV Cutaway, 1995 Ford Econoline, 1995 Ford Cutaway, and 1995 Ford Club Wagon. However, it is still accessible from the selected car via links, so may be relevant.

Start and run engine. Observe polyvinyl chloride hose while switching selector valve between tanks. If bubbles are present in both tank positions, go to CHECK HOSE CONNECTIONS test. If bubbles are present in only one tank position, go to next test.
