Re: Installed holley red fuel pump, still wont run.
The stock fuel system on an OBS
such as yours has a two stage mechanical fuel pump. It sucks fuel from the tanks, then feeds it to the fuel bowl, then back to the pump pressurized to the back of the heads. from there it feeds the injectors and at the front of the heads has 2 return lines that go to the fuel bowl where the pressure is regulated then the fuel is returned to the fuel tanks.
By putting the holly fuel pump to feed the fuel pump it wont necessarly fix your problem. As for removing all the lines, you can do this but i dont think that holley red fuel pump will be enough to support the proper fuel pressure. Look for posts on a Regulated Return Fuel System, this will help you convert the truck to E-Fuel and eliminate the mechanical pump and the fuel bowl.
