inline fuel pump booster

[Halon]

Like was said, there's a few options. BAP will just increase voltage to the single pump, causing it to flow more. Adding an inline external pump (dual pump in series) is another way t get more fuel to the injectors. Not sure about evo's, but twin intank pumps in parrallel is another option possibly. Pick your poison

He was thinking that an inline would be cheaper but it isn't. You need a large inline pump to get anywhere near the flow of two Walbros in parallel. A $190 Bosch vs a $90 Walbro.

In addition to larger injectors he'll need an afpr setup for most dual pump configurations--the only exception would be if he ran the second pump of an in-tank double pump on a Hobbs switch.
