Injector pop pressure

[FatFut]

I just got curious and opened one of my original injectors that I had changed a few years back. I was surprised to see how simple it was. Now I'm wondering what part is changed to increase the pop pressure? I have heard that it involves a shim, but not sure where the shim goes.

should be a shim in it under the spring

The shim is that(those) little washer looking pieces. And a pop tester.

 

[FatFut]

would that be wave washer under the nozzle(s)?

I got a pop tester if you need any help

Hey Marty, do you know where I could get some shims?

 

[DieselCash]

No, either AK or Leroy Diesel should. You could try the injection shop on the other side of Temple. It is right next to a Elementary School. I believe they are open for a short time today.

Here is a link:

I took my used purchase injectors there to be tested. They did it for free, since they were all bad.
