      Fuel System Enhancement. The AFE DFS780 Fuel System; Boost Activated is engineered to improve fuel delivery specifically for diesel trucks by activating the fuel pump only under boost conditions, which reduces wear and tear. This system increases reliability and performance by providing additional fuel pressure and flow during heavy engine loads.
