You should check the pressure before and after the shim. Any fuel rated gauge will work, but good ones are better. If you install a 90 degree fitting where the schrader valve is now, and reinstall the schrader, you can use a mechanics fuel pressure gauge to check it.
Can an engine compression tester be used to check the fuel pressure at the shraeder valve?
