It's all so to increase the fuel volume. It was all so upgraded with a walboro pump.

You can actually use the factory s10 pump . I wrote t he book before I found out the factory pump would supply enough pressure. BUT ! All you need to do do with a truck intake is run the fuel line directly to the fuel rail because the regulator is built into the fuel rail . You just need run a return line from the rail to the tank.
