I thought it would be good to post some pix of our VE fuel system. We make a CNC machined billet aluminum fuel hat that mounts two Walbro 255 LPH or Aeromotive 340 LPH pumps. It reuses the stock fuel "bucket", fuel level sender, and jet pump. It functions like stock in the tank but flows enough for nearly 1000HP.
To accommodate the fancy new Dual Pumper we have a couple of options to build up the rest of the fuel system. We offer a "returnless" style system that uses the stock fuel supply line on the car. It uses a Corvette C5 combination filter/regulator, some AN fittings, -6 hose, and bolts into the car. This has been dyno'd on one car at about 530rwhp with a TVS1900 and should be good for at least another 100hp on top of that. It's inexpensive and easy.
If you want to make the most HP we offer a full -8 return style system, complete with Aeromotive fuel rails. This is for the 6.0L and 6.2L (L76 and LS3) in the states. With this kit you get a regulator to mount in the engine bay, billet filter, all fittings and braided hose.
Here are a few pix of the gear for the VE:
Here is the Corvette type fuel system installed. The only part you can't see are the fittings on the sending unit at the tank.
