pre pump filters

THIS:

two: EAR-230108ERL 's

-8 35microns, $35 ea. pre pumps. then post pump run a 10m single filter up stream once you join the lines or dump it out of a surge tank.

on this note, would it be better to run the 10m filter as close to the fuel rail as you can for better flow upstream or just do it out back where the other filters, pumps, cell and shit are?
