What are the case numbers on a fuel injector telling me?
Can I get a part number from the case numbers?
Hello: I'm working on a 1995 C2500 with throttle body injection. One of the injectors is bad. I've learned it is a rebuilder. The PCM number is for a 4.3 6-cylinder, but it is an eight cylinder engine. The eighth VIN is an 'N' for a 7.4L.
The numbers on the case are RI-694 and 2320. The 'eye' may be a 'one.'
The injectors I've tried by application don't work. I've swapped ports and know that one good matching injector will fix the problem.
I've spent over two hours doing google searches and haven't been able to identify a correct part number for the working injector that I already have. I have learned that different manufacturers have the same numbers stamped on injectors for the same application. I'm thinking these numbers are an ISO or ASE identification? All I really need to know is the correct replacement part number, but
I'm really curious now. What are these case numbers telling me? Do any of the manufacturers or anyone else have cross reference tables?
While doing my google searches, I found a lot of people asking for injector identification based on these case numbers. I think this information would find good use for many others as well as myself.
Thanks all. JB
