Does anyone have a diagram that shows where the hoses for the soap tanks on a McCulloch FHH18A pressure washer should be connected to the tank selector? I took mine apart to clean it and neglected to make a diagram for reference. Now when I hook the garden hose to it and turn on the water one of the hoses pops off and water goes everywhere. And also can anyone tell me how the little spring and ball should be placed in the swivel fitting connected to the pump? I feel so stupid. Thanks.
