GAP carries the Wehrli Custom Fab WCF100260 CP3 Conversion Kit (Without Pump) you need for your 2011-2016 GM 6.6L Duramax LML. The CP4.2 injection pump found on your LML Duramax is known to be a common failure point of the fuel system. Even a small amount of contamination in your fuel system can ruin the pump's internal parts, leading to metal debris getting flushed throughout the entire fuel system. When the CP4 pump fails, it can lead to a lengthy repair that normally includes all new injectors, fuel system sensors, fuel lines, and complete cleaning of the fuel tank that can cost over $8,000.
Wehrli Custom Fab set out to develop a solution for this problem and came to market with the first CP3 Conversion kit in 2013. This American made kit provides improved compatibility with stock and lightly modified trucks and provides an excellent value when paired with an OEM 'LBZ style' CP3 pump. (See Related Items)

Nice to have
Color: Brown, Size: 10.2" x 8.4" x 1.8"
Good:
It's a good sized leather tray for the price. I'm able to keep my keys, wallet, tv remote, and watch flat within the box. There's not much else to say, it's a leather tray, it just... works. It gives me piece of mind knowing that I'll always find my accessories and belongings nicely tucked into this tray.
Bad:
I'm a fair reviewer, if a product wows me I'll say it wows me. This does not wow me in the craftsmanship department. The product I received contains the leather tray and a leather "floor". The leather floor is a separate piece that sits at the bottom of the tray which completes the complete leather look and provides some cushion to the things inside. This leather floor did not fit perfectly within the confines of the tray. One edge sits slightly tilted upward. To be completely fair, this is a very easy fix. I assumed that the stitching was simply applied too tightly and causes the floor to 'crunch'. I simply reduced the tightness of the stitching and it's perfect now. However, I cannot give it the full 5 star rating I wanted because not everyone is keen on solving issues like this. When people order things, I assume that most people would like a product that looks and feels great straight from the box.
Verdict:
Would still recommend. Despite this being a somewhat niche product it really helps with quality of life. I no longer have to go looking for my keys, wallet, or tv remote between my couch cushions. I know exactly where I'll find them every time and this saves an exponential amount of time in the mornings. As a bonus, the color is really nice and dark chocolate brown which goes with most things and leather is just a nice luxury to have.

A perfect catch y’all
Color: Dark Grey Shagreen, Size: 10.2" x 8.4" x 1.8"
I use this as a catch on on my dresser and it is sturdy and provides a bit of chicness and beauty that I can just throw all of my things in and keep it keep myself organized. It is leather, and well constructed so you can’t go wrong. And if you spill anything, just take a wet wipe and wipe it up. I highly recommend.

Holds stuff nicely - classic addition for the bureau!
Color: Brown, Size: 10.2" x 8.4" x 1.8"
Ordered this as a gift for my son, who always seems to have a small pile of "stuff" accumulating on his bureau.
He is not a fan of leather, so this tray was perfect! And it was a great value for the price.
Ordered it in brown. It has a nice feel to it and (color-wise has a rich tone).
Perfect for his keys, spare change he finds in his pockets, extra watchbands, whatever.
Makes a great gift! I definitely recommend!

Nice design
Color: Dark Grey Shagreen, Size: 10.2" x 8.4" x 1.8"
The design is nice and doesn’t take up too much space, but it holds a lot more than I expected. The materials feel sturdy and quality, and it looks great. It's made it so much easier to stay organized with our keys and wallets.
