Manufacturer Description

Improve your LML Duramax's reliability and fueling capability with a CP3 conversion. Since its introduction, the CP4 has proven to be less reliable and less capable than the CP3 used in previous Duramax platforms.

Failures of the CP4 are extremely costly and require replacement of the entire fuel system. Our kit provides you with OEM fit-and-finish features like a brand new Bosch CP3 with heavy duty 10mm cam, Fleece exclusive molded hoses for the fuel feed and return, high flow CP3 fuel fittings, and our valley feed line to support aftermarket lift pump applications.

Application Notes:
This kit has been tested for use in stock application trucks that did not utlize a fuel lift pump. For optimal performance, if the truck is equipped with a lift pump, the feed pressure to the CP3 should not exceed 2 psi.

Engine surging may be induced by the additional fuel pressure of a lift pump operating at pressures over 2 psi. For higher lift pump pressures, FCA table values will require adjustment.

Elegance and Practicality in a Lightweight Divider
Color: Mountains and Waters, Size: 4 Panel, Color: Mountains and Waters, Size: 4 Panel
Elegance and Practicality in a Lightweight Divider I recently acquired the 4 Panel Room Divider from the Furnnylane Store, opting for the Japanese mountainside print over the floral theme. Priced at $149.99, this piece not only promised functionality but also an aesthetic charm that piqued my interest. Upon arrival, the first thing I noticed was its impressive dimensions (63"W x 67"H), offering ample coverage for most standard spaces. Despite its substantial size, the divider is surprisingly lightweight, making it a breeze to move and adjust as needed throughout my home. The double-faced design is a standout feature, providing 100% blackout on both sides, which is ideal for privacy or blocking out unwanted light. This aspect was particularly appealing to me as I was looking for a solution to minimize nighttime light intrusion. The divider excels in this regard, effectively blocking and diffusing light to create a more comfortable sleeping environment. From a design perspective, the Japanese mountainside print adds a serene and picturesque element to the room. While the materials are not what one might consider artisanal, the overall look and feel of the divider are quite lovely, enhancing the room's aesthetic without overpowering it. The room divider's foldable design adds to its convenience, allowing for easy storage when not in use. It requires no assembly, which is a significant plus for those who prefer hassle-free products. The natural pinewood frame, free from chemical paints and non-toxic glues, aligns with my preference for safer, more environmentally friendly home decor. In terms of versatility, this divider has proven to be a multifaceted addition to my home. It serves not only as a practical room separator but also as a decorative piece that brings a touch of elegance and tranquility to any space it occupies. Overall, the 4 Panel Room Divider from Furnnylane is a commendable blend of form and function. Its lightweight nature, combined with the beautiful Japanese mountainside print, offers both practicality and visual appeal. While the materials may not be of the highest artisan quality, they do not detract from the divider's charm and effectiveness. This piece has been a delightful and functional addition to my home, and I would recommend it to anyone looking for an elegant solution to room separation or light blocking needs.

Nice room divider
Color: Colorful Landscape, Size: 6 Panel, Color: Colorful Landscape, Size: 6 Panel
I am pleased with this room divider. I was concerned that the art design might look blurry or cheap in person compared to online, but it doesn't. It looks really nice. In fact, I like it so much that I bought a second one as well. It arrived folded up - there is no assembly required - you simply unfold it and place it where you want. It's relatively light weight so it's easy to move. I also like that there is a different artwork design on each side. You have two choices; you can display whichever side you like more.

May cause respiratory issues
Color: Mountains and Waters, Size: 4 Panel
The painting on this panel is beautiful and quality has held up BUT I’m almost certain this contributed to respiratory issues. It was next to my bed for a year and I recently noticed it’s still shedding red/brown dust. The wood was clearly painted over and it makes me skeptical about the wood that was used. The panel itself feels like it’s made cardboard. If you’re sensitive or plan to place this panel in a main living area, I would not recommend
