The AirDog A4SPBD137 FP-150-4G Air/Fuel Separation System from GAP is the perfect upgrade for the fuel system on your 1989-1993 Dodge 5.9L 12V Diesel (Moderate To Extreme).
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 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.
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.
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.

Add these if you like to keep things moving 😉
Size: 81 Count (Pack of 1)
The taste is good but not great lol I take iron and sometimes it makes me a bit constipated so adding these to my everyday keeps things moving. No side effects. Easy chewing sometimes they clump together in the bottle but a good shake gets them apart.

Works and taste great!
Size: 81 Count (Pack of 1)
I don't understand how some people are saying the taste of these are bad, I think their good. It took me about a week to set on a amount to take every day and decided on 3, with the help from certain fruits and vegetables I go every day now. Only reason I have it 4 stars and not 5 is bc of the gas it gives. After taking the gummies for about 3 hrs it's Alot of gas and man 🤢 bad!! But these gummies work and I'm not constipated anymore 😊

High quality fiber
Size: 81 Count (Pack of 1)
Excellent fiber. I take it twice a day so it does fast but it's the best fiber gummy I've used in terms of results. Some of the flavors aren't my favorite but they're all palatable. I like the gummies because otherwise I forget to take them. It's hard to remember to take them exactly between other meds so having these sit out helps.
