I got my 2000 f250 7.3 with 326000 on her and My number 2 injector is failing so i am doing a compression check and was checking out the injectors and was wondering if they are stock or?

Really the only way to tell is have them flowed or pull one to see if it has a serial number from a builder on it.

Some injector builders engrave the hold down bracket.
