MFI pressure at injector

I have searched MFI topics, read the material posted on PP and have not found the fuel pressure to the injectors that open them and the fuel pressure to the MFI pump. Does anyone know and/or where was it in the reading material? We are checking the injectors and pump. Thanks for any help. Austen

Didi you check the tech articles? I thought it was in there somewhere. I believe that the opening pressure is about 213lbs. There is a tech article that talks about testing the injectors by holding the pressure just below that to see if they leak.

The numbers are given in several of the documents on Pelican's MFI Tips page ... including this one:
