ATS Twin Fueler System for the 2001 Duramax doubles the fueling capability when running large tunes and bigger injectors. The system is not only designed to work in conjunction with the factory CP3, but it also maximizes the system. Utilizing ported rail fitting, larger diameter high pressure fuel lines, and a true twin system, the ATS kit allows for huge amounts of power and reliability. When it comes to optimizing a Common Rail Injection System, rail pressure gets talked about a lot. Pressure is in fact extremely important, however, it is not the only important aspect. Equally, fuel volume is the actual additional amount of fuel you are able to add in to the cylinders during injection. This is going to to have massive impact on your final ability to create power. Ultimately, your truck needs fuel pressure to properly atomize the added fuel volume that you introduce. Not all modified CP3 kits or dual CP3 kits have this capability like the ATS Twin Fueler System does. Additionally, the billet aluminum wheel, is sized proportionally to the factory CP3, allowing better equalization of the rails. Generally, this will not matter so much as the regulators will control the amount of fuel regardless, however, it is attention to detail such as this that sets the ATS kit apart from the others.

  • Increased fuel volume throuout entire RPM range

    prettiest kit on the market but instructions could be better

    by Jason Hansen

    Fit and finish is the highest quality of any kit out there, with that being said, probably the most difficult kit to install too. Good instruction in the kit but don't lose them, they can be a bit confusing because they offer the parts and instuctions of routing the fuel supply two different ways but they don't really break up the two different ways very well in the instructions. My kit was the 2001 so you have to change the alternator bracket out too, re-route all the pulleys and belt tensioner and no more fuel test port. Wish install instructions detailed the two different ways to plumb it better and did not skip around as much as they do but, it is the prettiest kit available with true braided lines also there was no warning that you cannot run it with a race plug installed.
