Flex Hose Connections
In many cases it is convenient to connect the inline pressure
test hose into the fuel delivery system at a location where
a flexible rubber hose is secured to a steel fuel line using
a screw clamp. A special adapter set is included with the
MV5546 for installing the inline pressure test hose into this
type of connection. It includes a universal barb adapter, three
flexible hose adapters (1/4”, 5/16”, 3/8”), and four wing screw
clamps.
To install the flex hose adapters:
1. Follow the proper procedure under the setup instructions
to relieve the fuel pressure and prepare for disconnecting.
2. Loosen the screw clamp securing the rubber hose to the
steel fuel line on the vehicle’s fuel delivery system, and
carefully disconnect the rubber hose (Fig. 4).
3. Insert the universal barb adapter (#16) into the rubber
hose (Fig. 5) and tighten the hose clamp (Fig. 6).
