Lose that restrictive line from the fuel filter housing to the injection pump and let your fuel system flow at it's full potential! The GDP Big Line Kit for Jacobs equipped trucks is an excellent addition to our GFS Performance fuel systems. Gain 2-3 psi right where you need it, at the injection pump inlet!
The factory hard line from the fuel filter to the injection pump is less than 1/4" in diameter. Our system replaces the restrictive banjos and factory hard line with our custom stainless adapter, high flow banjo and full 3/8" line! Check out the photo above.
System includes stainless steel adapter, 90° PushLok fitting, High Flow Banjo and PushLok fitting for the CP-3 connection, Cummins sealing washers, 3/8" hose, clamps and a billet aluminum "T" for adding your fuel pressure sender.
Note: Only for 5.9 litre applications!
