Default ANOTHER fuel pump question

**I have searched already**


I have read around and cant seem to find out what I am wanting to hear, I have an 01 GMC with a 5.3 in it. I am in the process of bagging in and have gotten to the point that I need to invest in both a fuel cell and pump. I am planning on running an external pump but can't seem to find out the PSI I need to be running. Everywhere I have looked everyone says to run the Walbro 255. My first question, is that an external pump and if so is it enough PSI and lastly where do I purchase it at??
