What injectors does this fit?

I picked up another 9H1690 gauge for $10 the guy thought it was a car timing tool I'm glad I found. Well any way there was a injector cleaner drill bit in the box in the wraper still it's part number 7F1522 and I was wondering what injector nozzles it cleans.

Thanks, JR

7F1522 is 0.028 in. dia. and fits the 5-3/4 in. and 5-1/8 in. bore engines with capsule nozzles.

Thanks Old Magnet!!! Capsule Nozzles are the ones that 2U-13As and stuff use?

No, the 2U-13A uses the flat seat injectors.
This would be for the later D7's & D8's with the D339 and D342 engines.
