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 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 adapters and full 3/8" line. Check out the photo above.
System includes stainless steel adapters, 90° PushLok fittings, Cummins seal washers, 3/8" hose, clamps and a billet aluminum "T" for adding your fuel pressure sender.
