Nevermind spray pattern or what "lh is expecting". Remember that your fuel pump is working against both the base fuel pressure AND the boost pressure in a boost referenced fuel system.

An example:
with 55psi fuel pressure and 20psi boost a walbro gss341 only delivers around 45gph @12v. And ~55gph @13.5v.

A stock bosch inline pump for 7-series only delivers around 32gph at these pressure levels...
