seperate pump per rail, no "yblock" bullshit which impedes flow, no wasting the pumps energy by pumping fuel into a rail thats not being used.
Plus if i was going to go ***** out id get a fuel cell, but putting a fuel cell in the trunk requires the addition of a rear firewall per NHRA rules. not building a wall in my trunk. As for mounting a fuel cell where the stock tank goes, maybe ill get around to that, but that requires custom work talked to a bunch of guys about it a while back found a couple willing to do it with a sump and everything.
so a couple reasons, plus i havent seen many walbros completely fail seen some start outputing low volume but not to a degree that it blows the motor or causes problems with anything other then WOT.
if one or both of them die, then i'll take it from there, or if its still not enough fuel i'll get a fuel cell mounted underneath and just be done with it. but i had two brand new walbros sitting around so i figured i should use them

yea, i initially wanted a stock mounted fuel cell, but its an odd sized space and therefore would require custom fabbing, ive found a couple guys who would do it but it was obviously a premium price, so i figured what the hell ill see how this goes, if it doesnt work it isnt a problem to adapt to fuel cell, got the fittings already

btw sen2two this will only work on the s5 pump assembly for the s4 you will have to fabricate a completly custom one as for connecting the the pumps to the bulk head adatptor I'm pretty sure keV had to get a reducer of some sort an barbed hose fittings. If you doing this for an s4 I'd recommend a lrg external pump and a spliter then on the pump assembly you can use a nice lrg pre filter I have some pix of mine if needed. beprepared to spend alot of money on a full ss fuel system

mines also an s5...
i was trying to find -6an to a barbed fitting for underneath. havnt found it yet. what hose size is it going to the pump.
im using -6 push lock for the whole set up, i dont think i'll be needing -8 for what im doing.
