Description

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.

  • Increases Engine Efficiency
  • Incorporates Tried-And-True 4G Motor Design
  • 150 GPH Fuel Pump
  • Faster Throttle Response

Good fit
Color: Light Grey, Size: Medium
A nice vest and a true slim fit. Good quality for the price and no satin back, the material is used for the whole vest, allowing it to be worn without a jacket and still look smart. I am 6' 3" and 200lbs with a slim build, the Medium size fit like a glove, snug but not tight as a waistcoat should be.

Good Fit, Fold Lines
5'9, around 125-130 pounds, and the Small fit me just fine. Adjuster strap provides a great range of... adjustment. Good waistcoat if you are looking for something quick and cheap. With it being cheap, however, the material suffers. Due to it being folded while in shipping, there are seem lines going down the sides of the waistcoat which make it poke out and look awkward.
