AirDog A4SPBD136 FP-100-4G Air/Fuel Separation SystemUpgrade the fuel system on your 1989 1993 Dodge 5. 9L 12V Diesel (Stock To Moderate) with the AirDog A4SPBD136 FP 100 4G Air Fuel Separation System from GAP. Your diesel engine needs better fuel flow when you upgrade its parts and performance. Vacuum at the fuel pump and agitation in the fuel tank are both increased by higher fuel flows. This causes more air vapor to enter the fuel system and lowers the engine's performance. Injector barrel plunger
Upgrade the fuel system on your 1989-1993 Dodge 5.9L 12V Diesel (Stock To Moderate) with the AirDog A4SPBD136 FP-100-4G Air/Fuel Separation System from GAP.
Your diesel engine needs better fuel flow when you upgrade its parts and performance. Vacuum at the fuel pump and agitation in the fuel tank are both increased by higher fuel flows. This causes more air/vapor to enter the fuel system and lowers the engine's performance. Injector barrel/plunger assembly galling, pitting, and tip erosion can also be brought on by air and vapor. The AirDog eliminates air from the fuel that might harm your injectors permanently and keep your engine from operating as it should. Additionally, the AirDog offers the fuel pressures and flows your diesel engine needs to operate at peak efficiency.
This AirDog system incorporates the 4G motor they have been using for years with excellent success together with their conventional nonadjustable/high flow return base. By keeping this fundamental layout, AirDog is able to provide a reasonably priced system with a well-proven and dependable motor design.
AirDog has engineered this system to remove water, particulates, vapor, and entrained air from diesel fuel. This lift pump and filter system is what your vehicle needs to deliver clean fuel to your engine.
The AirDog operates by pulling fuel from the fuel tank containing entrained air/vapor, particulate contaminates and unknown quantities of moisture. Fuel passes through the water separator that removes water and large particulate contaminates. Next, the fuel with only entrained air/vapor and tiny particulate contaminates remaining, enters the fuel pump. Under positive pressure flow, the fuel passes through the fuel filter and the remaining particulate contaminates are caught and contained, the entrained air/vapor is also separated and returned to the tank. The clean fuel then flows at the proper pressures up to your engine. Each kit includes plumbing, hardware, wiring harness, mounting bracket, and all components needed for installation.

Worth it.

These shelves are great. They felt light in my hands but I can assure you they do hold their weight. As you can see I have lots of crystals on mine. They are easy to assemble and look nice. I recommend them.
