Default How does an inline pump boost lph after the stocker?

Can someone explain this to me how an inline can boost lph when the stocker can only pull it at a certain amount anyways, It almost seems as if the inline pump would take more fuel than the stocker could pump? The reason I ask this is because I'm trying to decide if I want to go with an inline 2nd pump or just 1 intank one.

hmm maybe I will just go with the external pump as the install will be much easier and if you can run a 125 dry shot and not lose any pressure thats pretty darn good.

External along with an internal works somewhat, because the external pump reduces the head pressure (resistance) that the stock pump has to deal with. Pump output (gpm) is a function of head pressure (delivered pressure). If you drop the delivered pressure then output volum in gpm goes up. The external then supplies the delivered pressure. Of course this only works up to a certain extent before the stocker just cant keep up. Inlines are a real bad idea for FI but somewhat ok of NA or nitrous setup.
