The fuel system for your LS swap can be as pricey or low-buck as you want it to be. If you're at 500, or less, horsepower then this is the hot ticket for feeding your newly installed LS engine. The tank is from Rock Auto (PN GM32AFI) and has been retrofitted for EFI duty complete with the sender and GM pump. At well under $500 it's a no brainer if you need a direct fit, baffled tank. This one is for a first-gen Camaro, but it has offerings for other Chevys as well. The other wallet-friendly part of our duo is this combination fuel filter and regulator from a C5 corvette (GM PN 10299146). It's not adjustable, but it's inexpensive and is the perfect match to the tank from Rock Auto. If you want something that can handle more power, is a custom size, or just looks a whole lot nicer, then companies like Rick's Hot Rods or Detroit Speed can sell you a sweet stainless tank.
