Home Made Diesel Polishing System Q

Hello All
I have a Whitby 42 with 3 70 gal tanks. I know one tank has some sediment but the boatyard wants $300 just to polish one tank. I am thinking of building a portable polishing system that I would insert into my line (Y valve prior to my existing Racor 500FG with shut off) to perform periodic polishing of tanks (beginning of season and maybe during long cruises). My idea is to purchase a second 500FG (60gph /15 psi max- love this filter), and a WALBRO FRB-20 (33 gph / 2-4 psi) with enough hose to run to my deck fill ports for recirculation. My questions are:
1) do I need a pressure regulator on the Walbro
2) running about 15 ft of hose from filter back to tank (~3 ft rise) would this be a problem
3) Walbro has a screen 70 micron filter at bottom - will this be an issue with clogging for general applications and will I need a pressure gauge on walbro
4) Am I missing something or does this seem reasonable
Thank you all
