AirDog A4SPBD109 FP-150-4G Air/Fuel Separation SystemThe AirDog A4SPBD109 FP 150 4G Air Fuel Separation System from GAP is the perfect upgrade for the fuel system on your 2019 2023 Ram 6. 7L Diesel (Moderate To Extreme). If you update the components and performance of your diesel engine, it needs better fuel flow. Higher fuel flows cause more agitation in the fuel tank and vacuum at the fuel pump. This decreases the performance of the engine by allowing more air and moisture to enter the fuel system.
The AirDog A4SPBD109 FP-150-4G Air/Fuel Separation System from GAP is the perfect upgrade for the fuel system on your 2019-2023 Ram 6.7L Diesel (Moderate To Extreme).
If you update the components and performance of your diesel engine, it needs better fuel flow. Higher fuel flows cause more agitation in the fuel tank and vacuum at the fuel pump. This decreases the performance of the engine by allowing more air and moisture to enter the fuel system. Air and vapor can also cause galling, pitting, and tip erosion in injector barrel/plunger assemblies. The AirDog removes air from the fuel to prevent long-term damage to your injectors and improper operation of your engine. The AirDog also provides the fuel pressures and flows required for your diesel engine to run as efficiently as possible.
This system was created by AirDog to remove water, pollutants, vapor, and entrained air from diesel fuel. This lift pump and filter system is necessary to provide a steady flow of clean fuel to your engine.
The 4G motor, which AirDog has been utilizing for years with great success, is included in this AirDog system, along with their customary non-adjustable/high flow return base. AirDog is able to offer a reasonably priced system with a tried-and-true and reliable motor design by maintaining this basic architecture.
The AirDog functions by drawing fuel from the fuel tank which contains entrained air/vapor, particle contaminants, and unidentified amounts of moisture. When the fuel passes through the water separator, water and large particle impurities are taken out of it. The fuel then reaches the fuel pump with the remaining entrained pollutants, air/vapor, and water. While the fuel passes through the fuel filter under positive pressure, the leftover particle pollutants are retained. The entrained air and vapor are separated and added back to the tank. The right pressures are then used to supply the clean fuel to your engine. Each kit includes all the plumbing, hardware, wiring, mounting brackets, and other installation-related parts needed.

A Really Nice Starter or Small Humidor
This is a really nice small or starter humidor kit for someone that buys a box or small assortment of cigars and needs a place to keep them maintained while working through them over a period of time. Sized right for this need, my picture shows 20 cigars stored with plenty of room left over for 5 to 10 more.
I added my own calibrated hygrometer with the hygrometer included with the humidor. This allowed me to capture a week long stream of data showing the seasoning process of the humidor as the internal relative humidity level slowly increased as the included crystal gel humidifier added water vapor to the humidor. I did top up the humidifier with the included cigar solution over this period but very little was needed.
After a week I had a stable internal humidity level near 70% so I added 20 cigars from my well maintained collection and all is well. As long as I follow the manufacturers instructions and keep the humidor out of direct sunlight, I believe it will provide a stable long term storage environment.
Prefilled humidifier, cigar solution, travel storage tubes, dropper and instructions were all well done. One thing I'll add is the provided hygrometer can be changed from degrees C to degrees F by pushing the on-off switch twice rapidly. This is not called out in the instructions. Also, I found the provided hygrometer to be off as compared to my calibrated hygrometer. This is common and once the offset is known it can be worked around. In my case the included hygrometer was reading 4% below my test hygrometer.
Fit, finish, and build quality of the humidor was very good. It looks good on the outside and appears to be sealing very well when closed to maintain a humidified internal environment. I very much appreciate the full coverage velvet-like cushion/pad on the bottom of the humidor to keep it from scratching a softer wood surface it is placed on.
Some quick notes on the hinge and hasp hardware. The humidor includes quadrant hinges which work really well for humidors. Happy to see them included. The locking hasp does hold the lid securely closed using a ball detent locking system. Should the humidor ever become too wet or you want to let the humidor air out a bit, the hasp can be used as a lid prop to allow some outside air to enter the humidor. Added a photo of this as my description is probably lacking.

Good quality humidor
This is a nice humidor for the cigar enjoyer. It feels well made, and it works well in controlling the humidity for your cigars. It is a standard, basic humidor, which does what it needs to do. The velvet bottom makes it create for keeping it from slipping off furniture or any other holding places you may store your cigars, while also protecting it from scratches and blemishes. The package comes with the humidor solution, the humidifier, and 3 travel cases for your cigars, which is a nice inclusion. It's a great option for those that enjoy a cigar every now and then, or for storage for a celebration. DXXULL does have other options for more enthusiastic cigar smokers. Overall, it's a great option that'll work for someone who wants to store some cigars at home, and keep their quality.

Not an expert, but this seems pretty nice!
Look, I'm not humidor expert but this seems like a suprisingly nice unit for the price. Everything fits together precisely, and the different parts seem solid with a nice finish. The felt on the bottom protects surface scratches. It's definitely air-tight; you can hear it when you open the lid. The included accessories (solution and travel cases) are a nice touch. I don't have another hygrometer to compare to this, but the included one seems to be accurate.

Super cute landing space for keys
Color: White 1 Pack, Size: 8" x 8" x 1.8", Color: White 1 Pack, Size: 8" x 8" x 1.8"
I always have trouble finding my keys and so it’s been very helpful to have a dedicated spot to easily throw them in when I get home. At first I thought it would be too big but it’s the perfect size for two wallets and keys, and it’s good quality albeit a bit expensive. The gold isn’t too shiny either, it’s a nice touch and it really reduces the look of clutter on your surfaces and helps it look more organized. It also doesn’t slip around.
