      Whipple fuel system routing

      Hello all, first post here. I’m building a c10 and it’s getting an ls3 with a 2.9 whipple. Blower is on order and I’m looking at getting my fuel system routed before putting the bed back on. I have a few questions and want to get some advice as I tend to massively over complicate and build stuff.

      some details:
      it’s a stage 2 ls3 built for boost
      2.9 whipple with Wegner front drive
      Dbw TB
      tank in bed with dual in tank pumps



      want to er on the side of too big as if I blow this up I will be going bigger and more bullet proof. It will be a driver with some AX trials on occasion.

      pump has 4 6an ports; pump 1, pump 2, return, and vent.

      my initial thoughts are p1/p2 6an out to a 6an-8an Y. Then 8 AN to th front going into a dual outlet fuel regulator (fitech 54002), then back to dual 6an lines to the rear of fuel rails with a crossover on the front of the rails. And a 6an return straight to pump.

      is this a solid setup OR what should I look at doing. I want to have a balance of performance but also look clean from a plumbing perspective.
