- Josh shows Steve Darnell from Welderup how the FASS Fuel System, Extreme Water Separator outperforms the competition! We take heavily contaminated diesel fuel and remove 99.96% of the water! This prevents water from entering your fuel injection system which can cause damage or even injection system failure! To see how well our Extreme Water Separator works, check out this video below!!
Literally buying an air dog just because of how shady this is.
guarenteed the filters are modified or bypassed LMFAO
Yeah for real a hydrophobic filter is a hydrophobic filter they will function the same 😅 especially since you don’t need to use the filters that come with them.
If that was true AIR DOG would be all over them for false advertising, I believe it.
This video is 4 years old. @trevorjaster4072
I did 😆 🤣. Fass has had issues with their pumps
I have had a Fast fuel system on my 1999 Dodge diesel for 18yrs and all I do is change the filter's every 2 to 3 yrs, Yes I would damn sure recommend this product.
Thanks great to see this I just bought mine for my 06 5.9 247,000 miles second time having issue with the stock lift pump so I ordered the 165 fass with sump. Excited to install.
A pig is used to clean oil pipelines. When refineries distribute fuels to tank farms there is no pig used.
Contaminated fuels are pumped into slop tanks that gets hauled back to the refineries.
Fuels at tank farms are continually tested after transfer to check quality
At the end of the day it’s just filters, but I definitely want a filter that can release the water and not have to change it every time
So they are showing the difference in filters not pumps... You can always change a filter
After watching this video, I’ve decided which system to buy. Thanks! The air dog should be here in a few days.
After seeing all those air bubbles defiantly going with the air dog I would like to see this done with clean fuel to compare the air separation of each pump
They also have the returns blocked off. When they are routed you get basically no air out of the fass
I have tested both on my 07 5.9 Cummins and they both work great however price point and customer service is so much better on the air dog I wouldn’t even consider the fass system and just seeing then use a separate air dog with no filters on it in behind the stand makes the fass brand possibly the shadiest diesel brand on the market don’t believe me call them and try to get customer service on any products
Thank you!!
AIR DOG Staff are some of the most friendly professionals and knowledgeable about their products I have their systems on my 02 and 04.5 cummins and they have stood by their products. Highly recommended. Idk anything about Fass systems. Never needed to
Yeah this test is rigged lol
Where did you see them using and air dog with no filter?
Had a warn out 200gph old style Airdog on the truck I bought. They worked me a new motor and rebuild kit, and I modified it to run Cat filters and Baldwin water separator with dump.
Customer service and treating people right is air dogs advertising.
Running a separator with no dump is not normal in heavy diesel equipment.
I've been using the airdog for over 2 years now, zero issues so I'll stay with what works
Good choice , FASS became obsolete about 10 years ago
Demonstrate it with caterpillar filters...
Are they good?
350 orange crush yes
@@BetterDegree7 AGREED! 👍
Cat filters all the way, I agree , can’t be beat !!!
Which cat filters numbers fit both of Airdog?
If your fuel had that much water in it, sue someone 🤣🤣🤣
a good fuel pump should not be putting air in the fuel like fass just did in the video
This test was demonstrating how FASS uses better quality filters.
@@toxic-performance I'd like to see filters on the Air dog, not empty canisters. Laughable!!
@@toxic-performance its a Fuel Air Separator System.. there should not be big bursts of bubbles in the fuel line
My buddy’s fass is trash be rebuilt by fass many times
@@toxic-performance crap product
Dang no wonder my diesel truck would jerk sometime when I’m in the pedal 😭 every since I switched to air dog I’ve been dogging it and had no issues 🫡
Carter lasted over 200,000 miles, and was still making pressure.
Airdog lasted 20,000, and just flat croaked.
My fass seems to always pop fuses and let air in and gel up… could be my fault my truck does sit for periods of time in Minnesota winter here and there I just feel like I shouldn’t be going through filters and fuses so often
Fass marketing is always so terrible I always buy AirDog solely based on that. They are almost the exact same system.
Wanted to see and independent not to say fass would jeopardize air dog ??? For profit so I think it could be biased
How do we know the airdog setup wasn’t sabotaged or altered prior? Are they really that lesser of a product?
Well, I was in looking around for which system to use and I'll definitly be going Airdog. This is so shady and you are obviously controlling the results.
Isn’t the problem that your filter swells when it gets water in? It means you have to change it and the other one can release the water?
Ya the pump behind the air dog side is moving the fuel with no filters
does it also strip out the hot shots fuel additive?
Doesn’t it have to do more with the filters than anything? Pump is a pump right
a pump is definatly not a pump. i think the test is rigged to demonstrate "fass filters better than everything" and hollowed out air dog filters............ you're supposed to drain a fuel water seperator once a week or sooner generally. so with a FASS you replace a filters once a week? not to mention that
they were indeed using the FASS and Airdog Pumps even if they used the air dog without filters or rigged filters.... you can thee the Airiation (the amount of air pumped into the fuel) on the FASS product........ its far far worse to have bursts of air pumped straight into your fuel lines than it is to have a little water. lets not forget FASS quality control is horrible. they have good customer service though. but Air Dog has Extremly good customer service. and Really high quality control......... i've had an Air dog lift pump on my truck since 2008. had 0 issues from it. still delivers as much fuel pressure as advertised. 230k miles later
Weird I've never seen orange diesel🤣🤣🤣my airdog has been flawless works great. Seriously that slight difference in color between the two would be unnoticeable as far as performance
Why was there any air after it ran through the FASS ?
I can't focus on the fuel pumps cause of that animation of the injector 1/2 down the cylinder
The only reason why I would purchase either of these is to get the air out of the fuel but obviously the Fass doesn’t do a very good job at all. Starting to think both are a waste of money.
If I have an airdog can I run the FASS filter?
It's weird having a water separator with no drain at the bottom of it..
seth watkins you’d think AirDog would have had lawsuit after lawsuit for false advertising if this is how their water separator performs. Kinda fishy.
MuffinB0x yeah i’m not buying it. not even a little and i have a fass
One I'm use to all have glass bowl or plastic bull at the bottom of the filter or the styem so u can drain it
Not shitting on a dog…. But just had my 2nd one fail in under 10,000 miles. May try a fass this time. Really brushless is where it’s at.
Fass and airdog motors are made by the same mfg lol
Bruh I had to go get some orange juice after watching this😂
Soooo the product from Fass your pushing is one without the water separator drain valve, and it’s also not even for “on road” use. It’s only rated for transfer tanks with a tendency to clog up and blow fuses (on our trucks) and fry the pump motor. Good call, I’ll go with the one on the right aaand another retailer! Good try on the product push though. FYI, Fass purchased a stake in Alligator diesel, so I’ll stay away from those guys too! ✌🏼
Facts my boy, funny how all it takes is a customer review and the cats out of the bag. Fass i pass.
The new at this time FASS water seperator had issues from what i was told left particles that the filters couldn't filter. Thatbis why my #8 injector got clogged and then became a plasma cutter popping a hole through my piston.
Per mechanics words. FASS still hasn't committed on my email i sent them two years ago. Ruined my brand new engine of 15,000 miles. I haven't fixed it since 😢
This video did not have the effect that they were shooting for!😮
Why the hoses go through back? Special design?
Ran air dog of every truck we have owned. Great product !
So many opportunities for shadiness at a trade show, as we can't inspect them in person.
So how about I just put FASS filters on my airdog system??
Or run cat filters
Been running an airdog 150 for 5 years 0 problems. 900hp 80k miles 0 issues.
watcha running under the hood? and in the trans 🤣
@@jopewsobviously bud light in the tranny
I HAVE AIR DOG!!! AIR DOG ALL DAY!!!!!!!! FASS IS A SLIMEY COMPANY AFTER WATCHING THIS.....LOL P.S. NICE LITTLE STUNT FASS #BIGFACTS
Ya and the fit and finish of a air dog is 2ng to none
Why do they not show all the piping?
Cause they're pumping out of a different vessel. You can clearly see the pump in the back, on the right hand side...
Love my airdog, my buddy bought a fass and tried to run it off the pickup like my airdog, and his truck would die at half tank. He decided to just buy a new tank with a sump to kake it work right. No such issues with my airdog.
your buddies pick up was probably disintegrated they usually are
Probelm was no sump in the first place😂 if you do it from the top you need it longer with v cuts
Need an upgraded draw straw . Or beans sump I run an air dog 150 and a beans sump with return line I bypassed the stock fuel filter and removed it from the truck going from the lift pump straight to the vp44 injection pump. on my 99 Cummins you can also use Cat fuel filters
@@adrenalinenjunkyes they like to break I just use a beans sump so I didn't have to drop the tank and install a new draw straw .. works flawlessly
That system think seen shown before. AWSOME Idea for those people dont know what getting fuel wise or say the person fills up a fuel cell for extra fuel.
I was waiting for the studio audience to start clapping like an old infomercial
I have had a airdog 100 on my truck for years now and I've had no problems!!! I think I'll keep my airdog
I just bought the 100 4g, everyone says get a 165, seemed like over kill to me though.
Lots of air, glad it pulls the water out. But that air isn’t great
They forgot one problem. Fass motors scream louder and a pissed off child and burn up about every 2months.
I Run a fass fuel pump on my duramax have no complains 😊
Really happy with my AirDog purchase after this lol
I thought air is supposed to be removed with FASS
A little bit of air???? I’ve seen less bubbles from a saltwater fish tank. DaYuM!
If you fuel up at any well used fuel stop you will be fine and there is no more mom and pop shops and the all stay in plastic tanks with no water .
Fass has a ton of air in the system
thanks for making my choice easy. defintely never going to buy any of your products
I'd love to see the air dog with the fass filters.....
The filters are the only thing doing the work on these systems you can get better filtere from fleet gaurd than either company sells
The filters are great until you figure out they’re not meant to be ran on a vehicle
@@PaulMcClellanmn pretty shady that theres like 0 filtration on the airdog and i know their filters to be excellent quality. but i stopped using them i use only Donaldson Filters. if i can't get any i get CAT filters on my air dog........... it just disturbs me. the test has to be rigged....... and even if its not... bursts of air into the fuel lines is way worse for your engine than a little water contamination. and the fact the Fass system has no drain vavle / fuel water seperator. you're technically supposed to Drain a fuel water seperator atleast 1 time a week before operation. so you're supposed to replace the FASS filters every week or sooner?
@@PaulMcClellanmn another thing to point out. a channel i watch. called "show me repair" did a video diagnosing a 7.3 powerstroke no start in a excursion. the quality control on the fass Product just isn't there. it was assembled new without a key componet to make it work properly.
You can clearly see a separate motor with no filters on it behind the airdog tank and not behind the fass one. Their just pumping the same fuel into the airdog tank and not running it through filters at all. Scams
Hahaha yeah just noticed it! Wow I have an air dog on mine no issues
😂
I'm pretty sure that's the circulation pump for keeping the center tank aerated.
Even with the air....isn't it supposed to be removing that?? 🤣
The return was blocked off. That's where the air is separated out. This is just to show the water separation.
Been having problems with my FASS since installed & their customer service acts like assholes. Their system pulls in air & my truck will die while driving with a trailer. Scary shit IM Buying an AIRDOG
I didn’t realize a pig was used to push product through 🤣🤣🤦🏼♂️
😂😂😂
its a tank filter it can completely faill by pluging up
However those fass filters don't go on trucks or any engine.
That's right they go in the trash
Air dog is whey quieter then fass pump
Fass has a water separator with no drain. So what happens to the water ?
Also josh works for fass so this is a bias test to me
Well see theres a fuse that blows and thats when you know that you have to change your filter on the side of the road more than likely with no filter or extra fuse..... OH AND YOUR INJECTORS LOVE WHEN THEY RUN OUT OF FUEL BY THE WAY...
I'm here to read the comments
Fass. You might as well take this video down. We can clearly see the independent motor on the air dog side. You did not run that contaminated fuel through the Air dog! Come on man don’t lie to gain customers that’s BS
That was a pump to mis big tank there is another video were he shows it
This is shady. I do NOT believe air dog would perform that bad. I do believe that airdog was running without filters.
Oh the comments!! 😊
What about HydroDiesel
it is water and diesel with an additive that keeps the mix emulsified and people are reporting more power , cleaner engines. longer lasting engines , better fuel economy, better price of course since you are basically watering down your diesel. It looks almost like milk with a white color to it and doesnt require any modification to your existing engine. I saw a channel on here do a side by side comparison and I was very impressed with the hydrodiesels prefromance.
Airdog with a CAT filter.. all you need
This issue between sumps and top fed is a no brainer. Anyone with any sense of the laws of physics knows sludge and heavy particles seek the lowest point. You’re just sucking all that in and IDGAF how good your filter is, particles will get thru. Best bet is to leave that crap on the bottom and you should never go below a 1/4 tank anyway. Unless you a poor MF’a which you shouldn’t have a diesel to begin with.
air dog it is !
Damn! You mean I can't fill up with water anymore damn it
What a bs test. The AirDog in no way leaves that much water. Shady, shady shady.
Another paid endorsement
Lol, "even with the air in it"
My fast system has been outstanding
Haha using a pig to push fuel in a pipeline. Wow
Two words,I'm CONVINCED!
I may not be a smart man, but isn’t diesel fuel typically green?…. Just saying
With my experience with fass I wouldn't buy their product if they were the only product on the Shelf
a early style HFCM with a fuel heater on the 6.0 powerstroke is more reliable than a FASS product. to name a few things it does better. it lasts longer it seperates air out of the fuel. it warms the fuel. it performs "fuel polishing" of the fuel it filters it sends some back to the tank. oh and its service able and has a built in water in fuel sensor.
Such so over priced stuff when every body’s stuff does the same at 1/3 the price !!
I want a legit video of them showing the lines and if it's legit they won't be scared to show their legit.. could've been hiding a crap tank some place.
Yea we know this video is a sham
There using the particle separation filter not the water separation filter on the air dog so it’s not gonna separate water the same obviously
The Montana remarks are BS. … a Montanan.
Cat filters ftw
Ya know.... I tested these myself, and got the exact opposite results. Wonder if I need a d list youtube celebrity to stand next to my expirment in order to change the results of my test???? Oh wait... I clearly did it wrong because these are experts, the algorithm even says so 🤣
Wow, not everyday you see this level of bullshit. Just for this, I’m buying another Airdog.
Air Dog definitely after seeing this video.
Airdog all the way. You two have slanted eye's. WHATEVER YOU BUY, DO NOT BUY AN AFE PUMP.
People listening to him have absolutely no idea what he was talking about when he said pig pushing fuel threw the line hahahaha.
Also the air dog isn’t set up properly there should be a return line that returns fuel water and air back to the tank to be cleaned again and only pure fuel should go the the cp3
Pigging is part of my job, this dude knows exactly what he was saying.
@@kevinlastair9808 that’s in a pipe line there is a pig separating each type of fuel being pushed but in a fuel pump from a tank there is no “pig”
@@Justthemow for what’s it worth, what I got from that his statement……is that when pigging you get trash, (called the envelope) and it can make its way into holding tank.
“Separating fluids” would be like batching, for chemical treatment like a corrosion inhibitor or Boicide for killing bugs.
But yes, his comment prolly didn’t makes since to 99% of the listeners.
If this so true why is it I still see crack injector nozzles ;)
Clowns.
Airdog and FASS are both made by the same company in the same factory.
Airdog all the way
And this isn't the first time fass has pulled shady ass marketing stunts
AIRDOG!!! 🇺🇸🇺🇸🇺🇸
What happens when that filter is full of water and stops flowing fuel? Little water vs no fuel? Air dog all the way! SMH way to show yourself as an ass company.
Bias
This guy knows nothing about pipelines.
Poor sale
Bull, the filter is a different type. Their filter is an overpriced Fleetguard with their name on it. There are separaters with drains an without and they filter differently. This test compares oranges with apples. Disiving
Fake news
Need Trump come to straighten out a fake Fass junk
