depends on how you feel about having a container of fuel pressurized to 50+psi inside the car. ive never been a fan, which is why I made the RRP. By putting it inside the fuel tank, it is able to function effectively without building up internal pressure. external surge cans which overflow to venturi's will inherently pressurize, for if they do not, the venturi's will not work, and you will fuel starve regardless of the surge can, as the surge can itself would be starved of fuel when the in-tank module isnt sending it anything.

In other applications, the run-of-the-mill external surge can like the radium is the go-to solution. In cars with return venturi's, theres a little more thought to put into it.
