DURAMAX DIESEL
Injector Return Fitting
Fits:
2011 - 2016 6.6L Duramax
Note: This listing is for (1) Fitting, (1) Foot of hose, and clamps. Three fittings are shown above. You will need to select the fitting you need from the options below when purchasing.
Were
you replacing an injector and accidentally broke a fuel injector return
line connector? It is very easy to do as they are plastic and when they
get full of grit and grime can be very challenging to release. In the
past, your only option was to buy the complete fuel return hose assembly
which runs over $150 from GM - not to mention that it is quite a task
to install!
Save
well over $100 and several hours with our replacement return connector!
We include one foot of high-quality self-sealing braided rubber return
line.
Instructions:
-
Very carefully remove the hose from the return connectors on either
side of the broken connector. An extremely sharp knife will allow you to
cut the hose and remove it without damaging or breaking the connector
the hose is being removed from. A Dremel type tool with a cutting disc
may also be employed with extreme caution to prevent damaging the
fitting.
-Pull
the locking sleeve up on the new return fitting and push the fitting
into place on the injector (a drop of clean oil will help it slide on
freely.) Push down on the locking sleeve to secure the fitting in
position.
-
Cut the return hose to length and very carefully push it into place on
each of the connection points. Use slow steady pressure in a straight
line to prevent breaking the return fittings. If necessary a drop of
clean engine oil will help the hose slide into place more easily.
- For extra assurance of secure connections (4) heavy duty USA Made hose clamps are included which can be installed as desired.
- Start the engine and check for any leaks
(Please note that Duramax cylinder numbering is Driver's side 2,4,6,8 front to back and Passenger's side 1,3,5,7 front to back.)
