I have a terrible headache with the ZD30 because I went to a mechanic and told me that the injectors were "damaged" and need to replace it. I went to a Diesel Lab and told me that on low pressure they are fine but on high pressure they don't work well. Are this injectors repairable? they told me that the top part of the injector is what really do the high pressure.

By the way, does anyone knows what means the different letters located on the Zexel Injectors (48-4120) of the ZD30?? I saw letter P, E, H, G on top of return line.

For your info there was a Ebay auction by someone who was selling reconditioned ZD30 injectors on an exchange basis, if I remember correctly for $185.........don't ask me how good they were as I made no inroads......

This would indicate that these units are repairable ??? ???
