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)

Best frother for many reasons
Color: Black
I spent a long time searching for the right frother because of how much I would be using it. I make coffees, teas and protein shakes daily. I needed something more high powered than normal. Ive had others that just dont get the job done and/or dont last. (the 3 others I tried were all free gifts with a purchase of coffees or teas online. So now that i was paying for one, i wanted something better with all the good features)
Its has 3 attachments for every possible use (if u dont know what the hook one is for, its great for protein drinks or any heavier powders u need to mix) but honestly all 3 attachments work for heavier powders due to the stronger motor. U can use it for cooking as well. The stand charger is super convenient and space saving. Multiple power/level settings. Definitely a quality item but with a bargain price. The cherry on top is the customer service. They're great! responsive and very helpful. Im definitely happy with this purchase and will now be looking into see what other products they have to offer. 🙂

Excellent customer service and good product.
Color: Black
Really like this frother a lot, with the attachments. Great price and works well. That being said, it suddenly stopped working after a few months, to my dismay. However, upon reaching out to the company, they replaced it very quickly. So I do recommend it!

Great frother, dumb charger
Color: Black
Works well. I got this to replace my battery powered milk frother from IKEA. I use it to make a protein shake every day. I just take a 16oz glass, fill it halfway with milk, add a scoop of protein powder, and mix it with the frother, using a combo of low and medium power, but realistically, low is all you need for that purpose. Been using it everyday for the past almost month since I got it, haven't had to recharge it and it's still working great.
The only reason I'm giving 4 stars instead of 5 is because the charger is micro USB. Not using USB-C in 2025 is honestly just insulting. Change that and you have a 5-star product.

10/10 – I’ve Already Bought Three!
Color: Black, Color: Black
I absolutely love this frother. It works in multiple ways and makes the perfect creamy blend every morning with my protein and collagen. It’s powerful, easy to use, and the charging stand is super convenient.
I loved it so much that I purchased one for myself, one for my mom, and one for my best friend’s mom.
What really impressed me was the customer service. Mine stopped working at full strength, and they walked me through troubleshooting. When that didn’t fix the issue, they immediately sent me a replacement. That level of support makes a huge difference.
Highly recommend — I’ll definitely be gifting more of these!
