The AirDog A4SPBD104 FP-150-4G Air/Fuel Separation System from GAP is the perfect upgrade for the fuel system on your 1998.5-2004 Dodge 5.9L 24V Diesel (Moderate To Extreme).

The AirDog draws fuel from the fuel tank that contains entrained air/vapor, particle contaminants, and unidentified amounts of moisture. The fuel passes through the water separator, which removes water and large particle pollutants. Only the entrained air/vapor and minor impurities remain when the fuel finally reaches the fuel pump. While the fuel is flowing through the fuel filter under positive pressure, any remaining particle impurities are collected and held. Air and vapor that were entrained are also separated and added back to the tank. Your engine then receives the clean fuel at the proper pressures. Each kit contains every piece of plumbing, hardware, wiring, mounting hardware, and other installation-related items.

This AirDog system combines their traditional non-adjustable/high flow return base with the 4G motor they have been utilizing for years with great success. By maintaining this basic architecture, AirDog is able to offer a cost-effective system with a tried-and-true and reliable motor design.

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.

Good for a quick backdrop
This works well for what I needed – a simple background for my kids’ online school. It’s lightweight and very easy to put together, and it stands up fine without needing to mount anything. The color is listed as black, but it’s more of a dark gray in person. Not a huge deal, just something to be aware of. It’s not super heavy duty, but it does the job for privacy and as a video backdrop. Overall, a good, portable divider that’s quick to set up and works well for light use.

Hard to assemble
Color: Grey
This is extremely hard to put together, but once its together it is pretty good. You will need to secure it to something. It falls over.
