      Description

      Boost Activated Fuel System. The AFE DFS780 Fuel System is designed to supplement the stock fuel pump during high load conditions by activating under boost. This provides increased fuel delivery capacity to support enhanced engine performance while reducing wear on the secondary pump by only engaging when needed.
