I am getting my KB 2.3L on Monday and along with that I bought a set of the 60# Injectors and Walbro 255lph Dual Fuel Pumps from LFP. I decided to get the injectors and pumps to feel a little safer since I am on a stock block still. I will be keeping boost around 10-14 psi. Here is my question... I had came across a tech article on KenneBell's website and the following information about the fuel system confused me. It said that the Lightning fuel system differs from the Cobra due to it having a regulator. And then it goes on to say WARNING: Leave the regulator, fuel lines, fuel pumps, and fuel rail stock. Now why is this? I know MANY people upgrade their pumps and injectors etc. Any help on this would be appreciated. Here is a link to the article and it is on page 4of9. http://kennebell.net/techinfo/ford-techinfo/Cobra_LightningTechTips.pdf
