Fass/AirDog
 

I was wondering whats the difference between the two of these?
they both look about the same
thanks
fuzzy

Price and warranty, and Name is the only thing i can think of thats different between them.

Most people use FASS because its FASS.

Ive heard that Air dog remade their pumps to be more compact and run quieter than before. But thats all i know as difference.

Big Difference Fuzzy,

The fass, which came on the market in 2003 uses the pump design and air separation of the 1996 Fuel Preporator, minus the primary or positive air separation feature. Ref. statements by Brad Ekstam on Feb. 16, 2007 when asked "the fuel Preporator without the air bleed port would operate in the same way as the FASS.." Brad replied "I am saying that you would be taking air out the same way we do".

Because the fass does not have the primary gas exit port, as does the Fuel Preporator AirDog, when the fass regulator closes to maintain pressure to the engine, nothing can return to the tank, everything must go to the engine, including air. The Fuel Preporator AirDog, because the primary gas exit port enters the return to tank port after the regulator, will always separate the air from fuel as long as there is the slightest positive pressure to the engine.

The AirDog, the smallest Fuel Preporator, with the positive or primary gas exit port and the 'Flow Dividers' added in 2002, can separate air from fuel at 150 gph.

The Fuel Preporator FP-200C, for class 8 trucks, die cast with an injected molded cover can separate air from fuel at 250 GPH and the FP-650 separates air from fuel at 650 GPH for the 14,200 cu. in. 7,000 hp locomotive and barge boat EMD engines.

The Fuel Preporator is approved for sale and use in California by CARB and has been tested and verified by CARB and EPA certified Olsen Ecological Labs of Fullerton, CA. under ISO 8178 8 Mode Test Criterion. Fuel Preporator performance for air separation horse power and torque inprovements and emission reductions has been tested and verified by independent testing at University of Illinois College of Engineering, University of Missouri School of Engineering Rolla Campus, University of W. VA. Engines Labs, NREC Power Systems Houma, LA. and Ministry of Transportation, Vehicle Inspectation, Toyko, Japan.

The Fuel Preporator Fuel Air Separation System has been on the market since March 15, 1993.

Small and compact,
The AirDog 100 and 150 are only 7.0" L X 3.2" W X 10.0" T.
The fass 150 is much larger, 8.6" L X 4.5" W X 14.1" T.

I hope this answers some of your questions.

:humm:

Thanks Charlie. :up:
The size is the first and most obvious thing. The AirDog is far smaller than the FASS. Next is the superior engineering design that is far more efficient at removing air and providing the advertised volume of fuel. Last but not least is the better performance. Take a look at the specs between the two systems. :up:

Thank you very good info there. one more question, with the airdog 150 does it remove the stock pump or help it?
thanks again

it will totally replace the OEM pump......you dont want it in there

good i want to get rid if the stock pump. also where do you get replacement filters?

Airdog

ok thanks. the airdog 150 with supply enought fuel for a set of 190cc injectors? i already have a stage1 fuel system on my truck.

i just read on another site, that the airdog with help the stock pump on a 6.0.

I would think so......Charlie wioll be better to answer that question fer ya

Yes, the 150 unit will supply enough fuel pressure to your IP for 190cc sticks.

You wouldnt want to run a superior pump in front of an inferior pump. Keeping the stock unit would just hinder the AirDog.

The filters used on the AirDog are industry standard units. You can find Fleet Guard replacements at just about any truck stop or diesel supply shop. Keep in mind that you wont need to replace the water separation filter but about every 5 years unless you get a lot of trashy fuel in your area.

Are the filters OEM only or are there local replacement filters that can be used?

Dix, what part of post #12 dont you understand? :ph: OHHhhhh thats right...Aaron told me you couldnt read and just looked at the pictures. Should I post up a pic for ya? :ha: :scared2:

Oops...sorry guys. I accidentally deleted our posts when I was trying to move them to a new thread. :sorry:

Its ok, we can start over again :)

lol

:ph:

Suckup

You know I don't read your posts! I was stuck looking at Whitmore's avatar anyway. Thanks Whit!

There are some major differences between the choices you spoke of. As for the air separation both the FASS and the Fuel Preporator must keep a positive flow of fuel (net positive suction head) to the demanding source. This is why it is very important to select the correct gph system. If the correct amount of pressure and fuel flow is not maintained, air will pass through either FASS or Fuel Preporator to the fuel injection system. Depending on the fuel requirements of the fuel system we have discovered it necessary to keep about 5 – 7 psi (if not more in some situations) to prevent cavitation.

FASS has over 27,000 systems in the field with less than a 3% failure rate. All issues with the FASS are addressed as they appear to the company with a pro-active attitude. As many products, the FASS is constantly improved.

The growing popularity is derived from the following:

• Reputation for setting the industry standards
• The first to have a 6 year warranty
• Precision machining (T-6061 billet aluminum)
• High quality motors w/High torque (196 – 406 oz inches of torque)
• High quality, concealed brushes
• Gerotor style pumps
• Tight pump assembly tolerances (+/- .001)
• Assembled through 25 point inspection
• “VacuSeal” technology, designed by me in 1995
• Cross-referenced filters with Fleetguard for the FASS 150 Series. Fleetguard currently has a water separator for the FASS 95; we are currently working with Fleetguard to release a cross-reference fuel filter for the 95 Series.

Flow & PSI Capabilites:

FASS 95 Series:

• 90 – 200gph
• 8 – 130+psi
• With air/vapor separation at these flows and pressures.
•


FASS 150 Series:

• 90 – 240gph
• 8 – 130+psi
• With air/vapor separation at these flows and pressures.



This statement is made with all fairness to the AirDog. Benefits can be seen from both products. We feel the time invested in the Research & Development of the FASS makes it a superior product.

Hello Dangerous Duramax,

I believe competition is great; it pushes us to strive for higher quality products!


The FASS 95 Series is slightly larger than the comparable Air Dog; here are the features and benefits of what you get with the FASS:

• Larger fuel filter - Longer fuel filter life



• Larger higher torque motors(196 – 406 oz inches of torque) -Benefits of using higher torque motors include:
a. Longer motor life
b. Longer filter life
c. Excellent extreme cold weather pumping capabilities
d. Higher flows and pressures while not exceeding optimum amperage draws

Note: Even our 95gph pumps have 196 oz inches of torque. The FASS 150 is also an excellent choice and installs nicely.


The FASS Systems have set the standards of “QUALITY”; this includes fuel air separation. Our customers have experienced this with the FASS Product line, from the 6 year warranty to the benefits of increase horsepower, fuel mileage, better throttle response, less cab noise, less vibration, lower egt’s and the list goes on and on, derived from fuel air separation (even at WOT).

Well I heard from a guy that sells the fass and is diesel worthy in my book has proof, test each item and the fass seems to have a bigger pump and a better one i am told. But that is all he said she said.

And sorry gees i posted this topic just a bit ago. So if anyone that can delete that one i posted please do so.

The FASS also has bigger filters

I was trying to stay out of this discussion, but its like keepin' a fox out of the henhouse!

Here's a big big difference, Glacier Diesel....did I stutter? Glacier Diesel now has AirDogs and Raptor Fuel Pumps featured as their new product line on their website, right along with their Walbro pump systems. I must tell you, I don't think I have met anyone more concerned about the quality of the products presented to his customers. Richard is a real gentleman.

Charlie

Is this the same Walboro pumps that dont include any warranty??????

After seeing two trucks, one running fass and the other airdog, I'm sold on the airdog. Plus they are based in Jeff City, only 30 minutes from home. You just cant beat that!
