Through testing we have discovered that twin CP3's require lower feed pressures (15 to 20 psi) to avoid high rail pressure codes at idle. Now we have the answer for maximum flow when running lower feed pressures. The GDP Big Line Kit for trucks with twins CP3's!
The factory hard lines 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!
System includes stainless steel adapters, 90 degrees PushLok fittings, Cummins seal washers, 3/8" hose, clamps and an optional billet aluminum "T" for adding your fuel pressure sender.
IMPORTANT NOTE: If your truck is equipped with the "Jacobs" brand exhaust brake and engine mounted vacuum pump please contact us.
