DONOT plumb the bypass before the 3way, it will take away the flow to the barrel valve, which is necessary to get fuel atomization at the nozzles
It's better if you mount the shutoff on the pump and tee the bypass off the shutoff, but since you already have your engine plumbed, see if you can't tee it off the shutoff where it's mounted. Plumb the fuel directly into the barrel valve with no restrictions, the bypass can also be tee'd off a fuel inlet line after the 3 way shutoff, but before the barrel valve. The idle bypass should have a poppet and a spring set with between 15 and 20lbs, no pills, and should only open in an idling position, the barrel valve should shut it down at 15/20% throttle.
When you get the hispeed bypass, we usually start those out at about 65lbs leakdown and work up or down depending on the egt reading. Again some people donot run these either. I have an adustable Kinsler which makes it easy.
Hope this helps, it confusing too me, but i know it's right
