Injectors: Flow Rate vs Color Coding | Doug Garriot | Tech Tip – VIDEO 2 Minutes

[Dennis]

This was a great video when Doug produced it but you cannot just go by color coding.

We are not only a repair center but we also have a fuel injector cleaning and testing center that services injectors for shops all over the U.S.  We actually own some of the machines Linder Tech used when Doug was working there.

We have injectors sent in all the time that have 2-3 different part #’s in the same engine where shops have thought they were all the same flow.  So not only do injectors that look the same have different flows but the fuel pressure behind the injectors can change the flow considerably. One other note on GDI injectors most of them are directional and have to be put in the exact position they were in originally or the spray is not in the proper place on the piston. This will cause a strange misfire that is hard to pinpoint since the cylinder does have spark and fuel.   fuelinjectionutah.com will give you other information and videos that you can show customers and technicians .
