Picking the right fuel pump

[EZ-E]

Ive been doing some research on fuel pumps and whats good and whats not good, between all that are available out there from one site to another over the internet, and the standing concensus seems to be that there are 2 good fuel pumps.

 

One being the Walbro GLS392, and there is the other which is a Bosch counterpart, but I couldnt find anything on the bosch unit with a part number.

 

All sites seemed to focus on one mainly great quality of the Bosch pump that the Walbro didnt have and that was the ability to run at a higher pressure without losing almost half of its volume.

 

IE. with the Walbro @ say just a random number anything above 60psi lph would drop dramatically where the Bosch still kept pumping true.

 

Now Im not one that is going for 5 or 600 hp but what would be the better pump of the two for a turbo motor that will in the end be at about 400hp in its final phase?

 

I would like your insights and also to see the reasons why you chose your fuel pump above any others.
