Fuel pump for 7.3 PSD WVO system

[jocko]

I am in the early stages of designing a 2 tank WVO conversion for my 2000 F250 7.3 PSD. I plan to do a second fuel system for the WVO and basically leave the diesel side as stock as possible. I want to do it this way (a)to keep from overworking the factory pump by making it pump WVO and (b)to provide redundancy in case of a failure in one of the systems. I have a couple questions:

(1)What fuel pump/regulator requirements do I have to consider? (eg, flow rate, pressure range, preferred type of impeller or whatever, etc)

(2)What are actual pump/regulator combinations that people have used in converting 7.3 PSD engines that have worked well? I have read that a couple of people have used and recommended the Mallory 110fi pump and corresponding 4305 regulator. Are there any other really good combinations I should look at?

I just got my wvo kit from frybrid. Check out the site. Lots of info.
