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.

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!
