Fass Fuel System

I have read evey post here on Air dog and FASS. I cannot make a decision to buy, what we need is pure proven scientific proof of results!!!!!!!!!!!!!!!!!!

 

you mean like the tobacco companies' scientific proof that cigarettes don't cause health issues?

 

So from what I have read and try to understand here, it may not give you better mpg, but it will be a big improvement on keeping your injectors from tearing and it does have a better idle. So in the long run it would save you money, by keeping your injectors cleaner and your fuel system more stabilized in the long run if I am understanding what the previous 14 1/2 pages have been about correct?

 

You should see a fuel economy improvement.

 

Thanks ironpony! Appreciate it very much

 

And if he doesn't, what then? And how much improvement if he does? There is no definitive answer to this for every application. It sure would be nice if there was some statistical analysis done to show the average improvement, if any, on each engine design. I realize that takes a lot of time and cost to do such things, but it is crap shoot otherwise. Those that have invested in something like this, are not exactly the unbiased in their opinions. If I shelled out what it costs for one of these, and it really didn't measure up to what I thought it should do, then it would be extremely difficult to admit it. And if there is an improvement, the amount determines the ROI. As for some idea that it protects injectors, could be, but I took a Cummins N-14 to 1.4 million and only replaced one injector with no other fuel system related issues. I took a ISX to just under a million and never replaced an injector, again, no other fuel system issues. And neither had a FASS or Air Dog on the engine, so any claims that it will definitively save injectors is spurious at best. Nothing more than another marketing claim with no statistical data to back it up.

 

Cowpie... no one is going to convince you of anything. If sliced bread was brand new, you'd be complaining about crumb wastage, LOL! There are enough satisfied users of this product (its been around for some time now) that I felt that there was a very good chance I'd see an improvement. And I have. The injector tolerances are much tighter on newer engines than on an N14 or even an ISX. The principle benefit of the FASS is getting dissolved air out of the fuel... which it does admirably.

Now I've seen a real improvement on my DD15. The long term fuel economy averages have held above 8 mpg since installation... that's something that previously would only be the case for a few weeks in the summer. Fuel consumption week over week has been much more consistent, the engine runs smoother and starts more easily. I've measured a real drop in the cost of fuel... both in real monetary terms (well before the fuel price drop,) and expressed as a percentage of gross revenue. That's been sustained through the summer and fall.

I've done enough process improvement studies across the years to know what a real improvement looks like. This is one of them.

 

You are correct, a scientific analysis would be great, wish the manufacturer wouldo spring for it. However, I did "feel an inprovement", at the time ran reefer aways heavy, felt more hp on hills, less downshifting.
I would counter you claim of several trucks running over million miles without jector problems with, did you ever hear of anyone that put fass on early in the trucks life have injector problems?
I just got a new truck, yes installing fass soon.

 

Thank you for the information i will be installing a fass soon, and air filter. It amazing just keeping you tire pressure at minimum pressure would do ,my tire pressure is 110 and i got a.03-.05 increase in mpg by just airing my tire to correct pressure, now i run light loads normally 15,000 +or- to fl from ga. So if you want to see a increase in mpg check tire pressure and easy off pedal!!!!!!

 

Interesting. This is Charlies daughter (Fuel Preporator) of 45 years and Brads (FASS) sister of 45 years. I have nothing to gain by this post except to clear up the "heresay" I read on these posts. Until last night, I had a relationship with my father. After reading the partial stories that I'm seeing on these blogs, I have opted to clear up my brothers reputation from my fathers version of how Fuel Preporator evolved over the last 20+ years.
I do realize this post is almost a year old, but things do need to be cleared up.
Father and son worked together on the Fuel Preporator from 1990 and throughout 1998. Yes, Dad did work on the Fuel Preporator (my other sibling)alone for the first year or so. As a son learns to work on cars, motorcycles, builds planes and go-carts from the knowledge of his father, he takes these lessons with him in life and can function on his own. Since Brad spent at least 7 years building the Fuel Preporator, helping to support and market the Fuel Preporator, I would hardly call the product Brad created a "Copycat". Seriously? Who is the copycat between McDonalds and Hardee's, GMC and Chevrolet??? This is a competitor. This is something Brad learned early in life, to build engines, go carts,,,,, and fuel air separation systems. If the system didn't work, wouldn't he be out of business? FASS is a device that removes air from diesel fuel.
Had FASS been found a copycat, my brother would have lost on all 16 counts of infringement. Dad sued Brad in Federal Court AND Federal Appeals Court and lost TWICE. Dad lost his suit on all 16 counts.
Jeremy, it's ok if dad doesn't approve.
I hope this clears this up.
