KOAL... ... ... never seen that on a Bosch type injector for our truck. Most are KDAL.
The number off the body from my '94 injectors reads as follows: KDAL 59 P12 260. Numbers off my 370 injectors are: KDAL 59 P14 389 18. And the tip # for them is 5969
I can't read the tip number for the 215 tips but I have the Bosch part number for the 215 injector tips from when I rebuilt the '94 injectors. The part number is: 0-433-175-081.
Stock tips are four holes and the 370s have 5 holes if I remember right.
Hope this helps
