Walbro 485 and ID1300s are a good combo.
Do not run the 450, or the ID1000s with ethanol as they will get destroyed. The 450 will fall apart from the inside out, and the ID1000s will corrode and clog. E85 is a very corrosive fuel and needs the components designed to withstand it.
The 1300s and 1700s where designed specifically to work with Ethanol fuels and not fail.
CJM Return kit is also a great option for your needs.
