How many people do this?

the reason for asking is I have most of the fuel system off of my old build laying around which consists of the following:

Aeromotive A1000
dual 8-an -> 10-an y-block.
inline 10-an pre pump filter
inline 10-an pre-rail filter
10-an feed
8-an return
ERL rail (oldie but a goodie, still new lol)
Aeromotive regulator

I don't really see the point in buying another walbro when I have everything here, except for the sump portion itself... I have a buddy that will weld the sump to my stock tank for free... so that's not the issue

I do drive my car pretty much everyday, sometimes at least 150+ miles at a time. I'm just concerned about reliability
