2011-2016 GM 6.6L DURAMAX LML (FOR TRUCKS WITH H&S TUNING)
The H&S Motorsports 131002 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 H&S 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 H&S 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 H&S 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 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? (CP3 not included)
1. The CP3 pump has been proven to be reliable. This pump technology has been used on the Cummins and Duramax platform for years.
2. 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.
3. 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.
4. 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 H&S Performance tuning device. Aftermarket lift pump such as an Airdog or FASS is required. Must be used with 6.7L Cummins CP3 Pump

My Niece dog loves it!
Size: 18in, Style: Sport
This ball launcher takes a bit of getting. used to, but it is really helpful for those of us who are not MLB pitchers! The launcher itself is a sturdy plastic that is not brittle yet not soft; when the ball is launched there is no destructive bending in the shaft. The handle is padded and ergonomically sound while the cup end cradles the ball but has cut-outs on each side for easy loading and unloading of the ball. It did take a bit of practice for me to get the hang of it, but for my husband and son it was much easier. The launcher works well to help us older, non-gifted athletes launch the ball farther and faster while saving the shoulder, elbow, and wrist (important if there is any arthritis). The ball fits nicely into the cup and releases easily.
The 2.5 size was too small for my Doberman, so we opted for the 3.5 in launcher. This smaller launcher and ball are now in the employ of my sister and her husband for their retriever-border collie mix, an 18 month old little fireball!. This is just the right size for her. My sister's husband has difficulty with arthritis and is neither quick on his feet nor able to stand very long. So the launcher comes in very handy. He can actually sit in a lawn chair and throw the ball repeatedly when their dog retrieves and returns it to him. That is a win- win!
Top 3 Likes:
-Easy to use
-Helps older pet owner
-Drives the ball farther and faster
Top 3 Dislikes:
-With repeated uses the edges of the launcher appear to get scuffed and scratched
-Some ingrained staining on the edges persists requiring scrubbing to remove
-There is a mild worry that with time the launcher may snap

My dog loves it
Size: 25in, Style: Sport
I am amazed at how far I can throw a tennis ball. My dog and I absolutely love this. What happens to work well with the squeaky balls?I get on amazon as well. I have one of these at home, And I keep another one in the truck.
Very durable, The balls have good bounce, My dog and I have a lot of fun with it. My dog doesn't chew much on balls, But this one seems like it's going to stand out, I love the versatility, Hey can handle almost ending ball that same size. Are you solid rubber bouncy balls, Squeak.
Ing tuba balls, Whiffle balls with all the holes in it, Even the squeaky chewing balls. As long as there are that same size.
love the product. I've been using them for a few years.

No returns… Confusing description
The seller doesn’t allow returns with this product. This product was much smaller than I expected, and I wouldn’t even re-gift it to a friend with a smaller dog. Why? Because they already tried a similar size and said it kept their hands clean… but gave them tennis elbow.
