I only know of Full Blow Motorsports that sell the internal housing for dual Walbro pumps but they're quite expensive. Does anyone know of any other stores that make internal housing for a 1g or do you all custom fab the setup?

Should I consider going to dual Bosch 044 or a single Aeromotive A1000? Is there really a benefit of going to dual pumps?
 
Do you setup it up like turboglenn did and welded another outlet for the other wally?

So what about hooking these up to a AFPR? What about the feed line? Do you make it into one or what?

I'm still new to this dual pump setup. Its hopefully in the future, but I like to plan ahead of time so I got everything right
 
I did it the basic way, one walboro in tank and another walboro in line, they are much quieter than the bosch, my afr and fuel pressure didn't change much, but I did have to re-tune wot, I would go with dual 255, e85 at high boost requires flow, keep it simple.
