12 Valves are fun, aren't they? With a few mechanical changes, you can unleash all kinds of power. If you keep pushing the limits of fueling, before long you will surpass the capabilities of the stock mechanical pump. In these instances, or if your stock pump is getting weak, its time to upgrade to an Airdog 4G lift pump.

AirDog I-4G is designed to operate at flows and pressures beyond the maximum requirements of the engine. It receives fuel under vacuum from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of water.

The fuel passes through the water separator which removes the large particulate contaminates that could damage or jam the gear rotor fuel pump. The fuel, with only entrained air/vapor and tiny particulate contaminates remaining enters the fuel pump.

The fuel, now under positive pressure flow, enters the fuel filter. As the fuel passes through the filter media and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated. Through the positive fuel air separation features of the patented AirDog I-4G the separated air/vapor is discharged from the filter and back to the fuel tank through the Primary Air/Vapor Discharge Port.

The fuel passing through the filter media is now free of contaminates and power robbing air/vapor. At pressures and flows able to meet the needs of the engine, it exits the fuel filter through two passageways. First, the fuel for the engine passes into the fuel pickup tube and on to the engine. Then, the excess fuel not needed by the engine recycles internally through the pressure regulator back to the water separator.

Unsure of whether you need the Airdog 100 or the Airdog 150? - Put it this way...if your truck is stock, or moderately stock(up to 500hp) you want the 100. If you've added a 100hp injectors or larger(500hp+), you will want the 150. If you have any questions, give us a call

Cooling and Sleek Feel
Size: 42D, Color: Glaze Purple - Unlined
Fits true to size. A little snug at first but the fabric eases up and relaxes as you wear it. And that’s true for the cups too. It loses its firm hold as you wear it. Don’t size up if it’s tight at first. For summer, its a very cooling lightweight sling. The fabric is sleek, smooth and cooling. (Not peached or padded) Doesnt offer much lift or shaping, but good enough for cooling comfort.

Won’t buy again. Unfortunately.
Size: 38F, Color: Beige - Unlined
The bra its self is comfortable. But it didn’t hold up. I wore it a few times a week since I got it and now hardly two months later the underwire is stabbing me.

Skims dupe
Size: 34DD, Color: Black- Unlined
This bra is amazing. It fits perfectly and is super comfortable throughout the day, providing great support without excessive padding. I’ve had this bra for a while now and have had no issues, and no wires are sticking out on the sides which tend to be a common issue after long wear of a bra, but not with this one I think it’s a great skims dupe

Perfect everyday bra
Size: 38D, Color: Beige - Unlined
This is by far the most comfortable everyday bra I’ve ever worn! The fabric is soft and breathable, offering just the right amount of support without feeling constricting. It’s perfect for all-day wear, and I barely notice it’s on. The fit is spot on, and I love that it’s simple yet functional for everyday use. It holds up well after washing too, keeping its shape and comfort. If you’re looking for a bra that combines comfort and practicality, this one is a winner!

Comfortable for everyday wear
Size: 42D, Color: Gentle Rose - Unlined
I wear a 40D and this bra provides solid support for everyday use. It’s comfortable enough for all-day wear and doesn’t dig in or feel restrictive. The fit is true to size, and the coverage is good, especially if you prefer something more full-coverage and secure. That said, I wouldn’t recommend it for high-impact or active use—it’s best suited for regular daily wear rather than workouts. Overall, a comfortable and reliable option if you’re looking for support without sacrificing comfort.
