A long ongoing debate has been prevalent in the fuel filtering scene, and the top contenders for delivering the best are AirDog and Fass.
This article talks about what they do and tries to determine which one of them is better. Read on to learn more.
Fuel-Air Separation Systems
First, consumers need to know what these two companies are doing. They provide fuel separation systems. If you want to maintain your fuel efficiency and good filtered engine, then you have the purest fuel possible.
This is where Fuel-Air Separation Systems come in. They filter the fuel that gets poured into the engine so that they become purer, eliminate contaminants, and deliver a better engine performance overall.
That is what AirDog and FASS have been competing for years. Both have been delivering tremendous products since their inception. Still, who tops among the two?
AirDog Fuel System
The video presents how the AirDog Fuel system works inside the engine. It shows that without the fuel filtration system, a huge amount of air would be present in the engine.
With the AirDog system on, it filters the air and only lets pure fuel into the engine.
AirDog and FASS Similarities
These determine what they both do correctly and show the importance of these principles in fuel-air separation.
- Both filter out contaminants like air, dirt, and vapor effectively out of your fuel.
- Very similar wiring schematic.
- Raises the lubrication giving an easy flow, preventing damage caused to the engine parts.
- Both fuel lines use lock adaptors so that they are seated better.
- Stops the popping of air bubbles at the tip to avoid breakage and engine heat-ups.
AirDog and FASS Differences
From being similar, they branch out in their own ways either to cut costs, improve efficiency, etc. For example:
- AirDog is comparatively better at cutting noise in the fuel lines. Meanwhile, FASS, although it seems quite inside, there are some minor buzzing noises heard on the outside.
- AirDog filtration needs two components for it to eliminate contaminants, while FASS only needs one part for it to work.
- FASS systems are 1.5 times bigger than AirDog systems. While AirDog wins in portability, FASS makes it up for durability
The steel powder coat on AirDog is more generic than that of FASS. It means that FASS generally has a quicker time installing their parts, while AirDog provides more flexibility on theirs.

How does lubrication affect the performance of the engine?
Better lubrication of the pumps prevents clogs and bubbles from forming in the engine. This is crucial in maintaining the vehicle’s performance as it determines the amount of fuel being pumped into it and how pure it is as it gets there.
What are the cons of both FASS and AirDog?
While both deliver outstanding performance in their products, these come at a cost for them to be able to be affordable to consumers.
For FASS, these include:
- Having a bulkier build
- Difficult installation due to unclear instructions
- Whirring noises sometimes can be heard
- For AirDog, these are where they cut corners:
- Shock absorption takes time before it loads
- AirDog systems tend to have less durability than FASS
- Some of the components are made of plastic
Which one is better, AirDog or FASS?
It really depends on what the consumer needs and their priorities. The wind stream framework comes at a lower cost than the FASS framework. Additionally, the noise cancellation is way better in AirDog’s.
Both the items function admirably against the impurities. The FASS system provides better durability than the AirDog system for better mileage. These can approach 800K miles. Likewise, they increment drive and force.

Is a FASS fuel system capable of increasing horsepower?
The most difficult parts are removing the fuel line from the tank and drilling the bracket holes. Then it’s all downhill from there. After a full day of driving, there should be anywhere from 10-20 HP gain with the FASS on dyno runs.
