A -8 to each pump will work. A -10 wouldn't hurt, but is probably a practical overkill. You'll want to mount the pumps low and as close to the cell as practical. Any pump will work best when it's "fed" with fuel and doesn't have to pull it up, against gravity, to it's inlet.

If you're running one pump to each rail, a -6 line for each pump will work. If you're merging the pumps into a single feed, I'd go -8.

yes the pumps are going to be merge. this is the plan so far from the sump tank a -8 line and 100 micron filter,from the filter a -8 Y merge the pump from the pump a -8 Y from the Y a 10 micron filter and from the filter a -8 to the fuel rail and a -6 to return.
