To release the connection, press and hold the release but-
ton on the side of the female quick-connect, while pulling
the connection apart (Fig. 11). Do not attempt to release the
quick-connect connection using a disconnect tool, as this may
damage the fitting. Replacement clips are included if needed.
Connection Types
The Mityvac MV5546 is capable of connecting to and testing
the following types of fuel systems:
1. All fuel injection systems that are factory equipped with
suitable fuel pressure test ports on the fuel rail (Schrader
valve ports).
2. Fuel injection systems that are equipped with a removable
fuel pressure inlet line that can utilize one of the many
adapters covered on Pages 5 & 6. Fuel injection systems
that are not equipped with a fuel pressure test port or a
removable pressure line but are equipped with a flexible
rubber hose line into the fuel rail.
The inline pressure test hose utilizes a special female quick-
connect fitting (Fig. 9). This fitting was selected because it
conforms to the SAE J2044 specification for fuel fittings, it is
a common fuel delivery system connection on which many
manufacturers are standardizing, and the connection releases
with a simple push-button action. No special tools are required
to disconnect the fittings.
The pressure gauge extension hose, as well as the adapters
and fittings that connect into the fuel system, have the com
-
plimenting male SAE J2044 endform (Fig. 10). To secure the
male to female connection, simply push the male endform into
the female quick-connect until it snaps securely into place
(Fig. 11). Always test the connection by trying to pull it apart
without pressing the release button.
