This high-flow fuel pump was supplied by Product Engineering and offers some of the most beneficial features around. This pump is designed for constant-duty usage and is backed by a hefty warranty. Using our Russell fittings, we plumbed out of the tank and also our return using -8 steel braided line. The hose on the right is the fuel input from the tank. The line next to it is the pump's bypass, which essentially bleeds off excess fuel back to the tank. We used #8 stainless steel flex line to run from the tank to the pump and back.
