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 Raptor Pump Systems. Gain psi right where you need it, at the injection pump inlet!
The factory fuel line from the fuel filter to the injection pump is pressed on nylon and very restrictive. Our system replaces the tiny factory fittings with our custom stainless adapters and full 3/8" line. Factory fittings are a mere .185" inside diameter as opposed to the GDP stainless fittings with a full .300" diameter. That a 250% increase in flow area thru the fittings! Check out the photo above.
System includes custom GDP stainless steel adapters, PushLok fittings, 3/8" hose, clamps and a billet aluminum "T" for adding your fuel pressure sender.
