Perkins CH12799 is the electronic unit injector with a white two stud solenoid cap, a cast rocker body with the plunger return spring and blue and red O rings on the barrel. It is used on Perkins 2800 series engines. This aftermarket version is made to the same mounting and connections as the original, so it fits where the old one came off.

Yes, it is a direct replacement for the Perkins CH12799 with the same fitting.
Often 5,000 to 10,000 hours, but much less on poor or wet fuel. Injectors are usually changed when they fail a test, not by hours.
Black or white smoke, a misfire or knock on one cylinder, hard starting, higher fuel use, or a high return leak or balance rate on test.
Not always. If the others pass a return leak or balance test, one can be changed. Where they are all high hours, a full set keeps the cylinders even.
Always. Fit a new copper washer and O-rings under every injector you remove. A reused washer leaks combustion gas and carbon packs the bore.
No. It is an aftermarket fuel injector made to replace the Perkins CH12799. It is not made by the original manufacturer; the number only shows what it replaces.
