I am installing my kit this wkend and have a small problem. I am going to be running with the 12:1 FMU for a while. What i needed to know is i have the Inline Pump that come with the kit and have also purchased a Walbro 255 Hp intake pump. Which pump should i use? I have a Ls motor in a 93 hatch, BUT still have the Dx pump in the tank. I have heard that if u use the inline pump with that little pump it will pull it dry so which pump or what to do for time being. I will only be running stock 6.5 psi until i upgrade to some larger injectors and a standalone. I just want to get the kit on and tuned.

 

I would recommend the stock intank with the inline, what will do you fine around 7psi

 

Make sure you have read, and understood, the dangers of high fuel pressure, and the capabilities of the stock fuel pump.
