Restore the fuel system in your 2011-2016 GM 6.6L Duramax LML/LGH with the XDP OER Series Fuel Return Line Assembly XD607. If you have dealt with a CP4 pump failure, debris and contamination have most likely worked their way throughout your fuel system.

When these metal shavings and other contaminants gets in the return line it can block the regulator and prevents adequate return fuel pressure. In the event of a failed CP4, it is recommended that you replace the entire fuel system, including the fuel return line, to help remove all debris and prevent future contamination of the new fuel system components.

In addition, rubber hoses are known to wear over time and can start to get hard or brittle, especially on higher mileage vehicles. Signs of degradation such as small cracks can begin to show up on the interior of the hose, although the exterior of the hose may look fine.

Love it but it stains
Color: Haze Blue, Size: 2 Pack Standard(20"X 26")
I love these but had to knock some stars down for a single reason. They are soft, the material is somehow both substantial and airy at the same time, and a smooth, silky (not satin), cozy texture. The color was exactly as pictured. The envelope style works great to keep my pillows covered. The fabric lays perfectly. I love sleeping on this pillow case. Took two stars off because every single atom of oil on my face stained it immediately and won't come out in the wash. Its not subtle. You can see anywhere my face has been, forever. I don't have some incredibly oily face or hair, I've never had this happen to another pillow case in my life.

Silky and Soothing
Color: Cream, Size: 2 Pack Queen(20"X 30")
I thought I was getting 1 of the queen sized but I got 2. I got these for my Pomeranian's fuzzy pillow. He's always hot and these are very cooling and very good quality. He loves them and are very comfortable for him. They totally transformed his shaggy old pillow. I used the larger body pillow covers to replace the covers I had. They matched my bedspread perfectly. I use 2 body pillows along the exterior wall in my bedroom where there is cold coming through the floor in the winter. I'm sure I will enjoy them in the summer when it's hot too!

Comfortable and stays cool
Color: White-cooling Basic, Size: Queen(Pack of 1)
Great pillow. When i opened it, i noticed a strange smell, i assumed its the smell of whatever they use to make the pillow stay cool. You have to fluff it for a good amount of time to make sure the cooling agent spreads well in the foam. Is what i assumed atleast. Its a perfect amount of softness for me. Pair it with some bamboo pillow cases and you got a good night of sleep
