the guys with surge tank setups..

i have a RCI 30l fuel cell that i am gona run as my tank, gona put a 1.5-2.0l surge in the engine bay, was gona run a walbro 255 as my pump from my surge to my fuel rail, but dont know what pump to run from the fuel cell to surge tank?

A normal intank pump will be just fine, It's only job is to keep the sergetank full.

dont have my intank pump anymore...and bosch pump you can recommend?
rb30det...1.5L-2.0L surge tank?

Any nissan replacement pump, 200sx,STI, Maxima....

ok cool!
those would all be intank pumps, can you use those externally in a inline setup?

You can but then rather get an inline pump....if for nissan you'll have to make some mods if you don't wanna run intank...
