I think this is the route im gonna go, why the 2 feed lines coming from the tank?
You can still put it after the rail under the car.Oh im building my own setup! But yeah that makes sense, never thought by passing the intank filter for just the second pump, im putting in a new intank filter and just running dual 450's with a return, im only shooting for 700-750whp so my setup should be able to supply that! But i think ill mount it under the car like your setup looks clean and less clutter in these tight engine bays, definitely makes it easy to route the return, hopefully it wont cause any issues not being after the rail. I guess i should be able to adjust it to compensate
