H&S Motorsports 131001 Dual High Pressure Fuel Kit 20007 15.00 H&S Motorsports 131001 Dual High Pressure Fuel Kit
$ 2799
The HandS Motorsports 131001 Dual High Pressure Fuel Kit is the ultimate in high pressure fuel supply for your 2011-2016 GM 6.6L Duramax LML. With over a year in development and testing HandS Motorsports has pushed this kit to the extreme and it still performs in even the most demanding conditions. Just as a quick reference for you diesel nuts out there, the engineers at HandS Performance were able to run 3800us (not recommended) of main injection duration on stock injectors without a drop in rail pressure. So what does that mean? Well, think about it this way; their off-the-shelf HOT tune commands around 1400us and is on the verge of draining the rail on a stock CP4-equipped truck. At 3800us, that is a 270% increase in fuel demand from their HOT tune and limit of the stock CP4. The HandS Motorsports Dual High Pressure Fuel Kit was able to maintain the commanded 29,000 PSI rail pressure without skipping a beat. So what's wrong with the factory CP4 fuel system? Nothing is necessarily WRONG with it, but the factory CP4 fuel pump by itself is only capable of providing enough fuel to safely produce around a maximum of 480-500 horsepower. Once your power goals exceed that 480-500 HP range, more fuel is an absolute requirement. Assuming your factory CP4 pump is in good condition, this kit is easily capable of producing 900+ HP worth of high pressure fuel supply. Will the CP3 pump ever wear out or deteriorate over time? The CP3 pump we include with the kit is a brand new OEM unit from Bosch. That's right, BRAND NEW, not a remanufactured unit like many shops sell. The key to ensuring the longevity of any high pressure fuel pump is by providing the high pressure fuel system with clean, waterless diesel fuel. Any fuel contamination that reaches the high pressure fuel system can be detrimental to reliability and performance. We highly recommend a fuel system such as Airdog or FASS for proper filtration and water-separation Why do we use a CP3 in instead of a CP4? The CP3 pump has been proven to be reliable. This pump technology has been used on the Cummins and Duramax platform for years. While the CP4 has the capability of delivering higher pressures, it lacks the volume of the CP3. With both pumps installed, you get the best of both worlds - high pressure and high volume. Price. With the CP4 being a newer pump, it is obviously more expensive. By saving on the pumps included with the kit, we can pass that savings directly on to the customer. If your fueling demands exceed what the stock CP3 and CP4 are capable of providing, one of our 6.7L Cummins 10MM Stroker pumps can easily be used as a replacement while still being able to re-use all fittings and lines included with the kit. Application Notes: Due to mounting interference, this will not fit trucks with dual alternators. The EGR cooler may need to be removed for use of this product. This product MUST be used in conjunction with custom tuning calibrations for an HandS Performance tuning device. Aftermarket lift pump such as an Airdog or FASS is required.
