LS Swap Kit for my G Body

The LS kit came with what I needed for my Malibu LS swap. Definitely get your YouTube education on tips and tricks when dealing with the cutting and installing fittings. Quick responses to emails from Hot Rod Fuel Hose before I ordered as well. One step closer to back in the road. Will be order again for my sons squarebody LS swap. Thanks

I used the ultimate fuel kit, very happy with the entire kit. I like that I didn’t have to coder the Walbro fuel pump electrical lines, it came with the connection. They answered my questions immediately, even on weekends. Definitely recommend!
