BBK SSI Intake Help!!!!!

[4jrfox]

Hello, I know after the fact that the BBK SSI intake wasnt the answer to all of my questions. Probablly, I wouldnt have purchased it looking back. However I have a question, the installation manual doesnt show which is high pressure and which is low pressure. The smaller line goes into the Fuel pressure regulator on the side of the fuel rail. And the larger line goes in the end of the fuel rail. Normally, I would guess the larger is high! But shouldnt the high pressure go into the fuel regulator and the return comes out of the end of the fuel rail after passing through the pressure regulator. Can you help which is which? I need to get this started today, please dont guess if you dont know for sure. Thankssssss, jrf

No, it goes the other way. fuel from the tank goes to the injectors, then the remaining go through the regulator, which decides how much to send back. That is how the pressure is regulated. I used to think it was backward too....
