Air Dog / FASS question

[MartyK]

Hello All,



I’m looking at replacing my factory in tank lift pump. From what I have read both the Air Dog and FASS put out between 15-17 psi. I did notice that Air Dog has a 30 psi version. My questions are:



• Is there any harm in going to 30 psi?

• What are the pros and cons of a 30 psi pump?



Thanks,

Marty

i have twin cps3 pumps and run alot of fuel through the beast and i only run a constant 12 for fuel pressure. when i ran more then about 15 i would get generic fuel delivery error codes. unless your plan on some large injectors i would stick with the regular kit and run a spring in the pump to keep fuel pressure around the 12 to 15 mark. i have never owned air dog but i know that diesel dan at fass will take care of you. give him a call and tell him what you want to do. he knows lift pumps and what you need for your aplication. i have fass pumps on both my cummins and wouldn't switch to anyone else because i have had good success with them and great customer service.

Marty,



My name is Jim and i work at FASS. We have all sorts of pumps that will fit your application. We can make any PSI from 12 PSI - 60 PSI. If you want, PM me with your information and i will give you a call and we can talk about what your trucks needs are.

In addition to the pressure, you should also pay attention to the flow ratings as well. The 30 psi pumps from both vendors will push 150+ GPH of fuel to your CP3. The question you need to ask yourself is do I need 150+ GPH fuel supplied to my CP3? Generally, the answer is no. The larger pressure/flow pumps are designed for heavily modified engines that will use that much fuel. If you are running a stock to moderately modified engine (like I see you have according to your sig. ), then lower pressure/flow pumps, about 90 - 100 GPH, should suffice.



To directly answer your questions, no I don't think there would be any harm to running a 30 psi pump. Your CP3 will probably spend a lot of time pushing excess fuel through the return line back in to your fuel tank. What are the pros and cons? The pros are that the bigger pumps use bigger filters. You don't have to change the larger filters quite as often. The cons are that the bigger pumps use bigger filters. The larger filters are more expensive as are the bigger pumps. If you want a happy medium, FASS makes a 150/95 pump. It's a 150 GPH rated pump that is turned down to only supply 95 GPH at about 15 - 17 psi. You get the benefit of using the larger filters without pushing way more fuel than you need to you CP3. The FASS 150/95 pump is also priced moderately as well. Best thing would be to give Jim at FASS a call.

On the FASS website they point to a heater port on their pump. Do they use the factory setup?

 

[MartyK]

What are the thoughts about running the FASS or Air Dog to the factory fuel canister to be able to utilize the factory heater and then a big line kit from the fuel canister to the CP3? Would it be ok to leave a filter in the canister? With an additional filter in the system would it make sense to go to the 30 psi unit? Would the filter hold up to the 30 psi fuel coming into it?

The stock fuel heater is only used to keep the stock filter from wacing in cold temps. If you go either AirDog or FASS you do NOT need the fuel heater!!

I apologize... I am fairly new on this site and i wasnt aware that it defaulted to that setting... Please try again and ill let you know if it worked or not:-laf

Usually you can run your engine coolant through those ports... It usually not needed but... Yes... . thats what those ports are for. They are marked with the letter "H"

With the FASS system you do not want to run to the stock filter housing. It will cause a major restriction and actually do damge to the filter housing. It cannot handle the volume that we will put to it. The FASS system actually filters 33% better than stock anyways so there is no need other than using the fuel heater in the filter housing which again... is not needed.

the above is true. With our system, After the pump has been running a little while (1-2 minutes) the heat of the system itself will heat the fuel enough to prevent icing.

 

[TimothyLong]

I'll second all of the above about not needing the factory fuel filter housing. If you still have a concern about gelling, I have seen a few in-line heaters here and there that you would install between the tank and the Fass but have no idea how well they work. You could also consider using a fuel additive that has extra anti-gelling agents in it.

 

[MartyK]

Thanks for all the replies.



What are you guys doing with the factory fuel line? Plug, remove, nothing... ?

What about the factory fuel filter canister? Plug, remove, nothing... ?



Lowfly, PM sent.

I thought I had my mind made up until I looked at the price difference. I looked on both websites, fassride and pureflowtechnologies, both products claim to do the same thing, use the same filters, have the same warranty, and are manufactured in the United States. Am I missing something? For $100. 00 difference in price, what am I getting?

 

[CodySanders]

it is brand prefference both companies are about the same from what i understand. the owner of one is father the owner of other is son. they use to be the same company but split up. fass was first then airdog i know nothing of airdog because i don't have any of there products. but i have had fass pumps on 4 trucks only one with a problem and that was the shop in utah's falt when they installed it. dan at fass helped me out found me the right part and fixed what the idiot that instaled it did wrong all over the phone in a city he didn't live in. thanks diesel dan

I too have this same question as I'm in the market. They both seem to take care of their customers when they have a problem, yet why $100?

I cannot speak on the Air Dog but i can tell you all about our system. It really is a matter of quaility. We use Aircraft grade aluminum in our pumps and our pumps are re-buildable. Our pumps come with a full kit which includes Fuel line, mounting Brackets, Mounting Hardware, wiring harness... . Everything you need to get going. All of our pumps come with a Lifetime warranty and you can call us here at the technical support hotline M-F 8a-5p Central time with any install questions. To me, Thats well with the $100 dollars extra. You get total customer support, durable and reliable product, complete kit and the knowledge that this should be the last lift pump you should EVER buy. That would be worth $100 bucks to me.

As I prepare for my AirDog installation this weekend I have inventoried parts, planned, and researched the install. I can tell you that my AirDog kit includes everything listed above (Fuel Line, Mounting Hardware/Brackets, Wiring Harness, etc. ). However, I am not sure if the AirDog is made of "Aircraft Grade Aluminum" (would need to give PureFlow a call to confirm). I purchased mainly because my brother's AirDog has been in service for 2+ years with 0 issues. During his install he reached someone at AirDog for installation support on a Sunday afternoon. I thought that was exceptional. Therefore, I will hang on to my $100 as fuel will probably be going up here soon.

What are the thoughts about running the FASS or Air Dog to the factory fuel canister to be able to utilize the factory heater and then a big line kit from the fuel canister to the CP3? Would it be ok to leave a filter in the canister? With an additional filter in the system would it make sense to go to the 30 psi unit? Would the filter hold up to the 30 psi fuel coming into it?

30psi is said to be the max limit on the OE canister, at 30psi you start to develop leaks. However keeping the OE canister and filter is a good idea. The reason being neither AD or FASS have f/w sep filters that meet OEM spec. The OE spec is 95% free and emulsified water removal, the AD is 50% free and 0% emulsifed (which is the same filter as the FASS 95). . The FASS 150 has unknown specs (even Fleetguard isn't sure what the ratings on f/w sep are). . The AD and the FASS 95 use an oddball thread/gasket size so you can upgrade slightly, but still not meet OE spec. . The 150 series FASS uses a very common 1-14 thread size so you can upgrade to a filter that meets OE spec. . So then you may remove the OE canister. . but you lose your heater (may or may not be a big deal) but you also lose you WIF sensor.



As far as actual filtration the AD is 5um absolute (despite what they tell you), the FASS is a hydraulic filter and is 3um absolute.

With the FASS system you do not want to run to the stock filter housing. It will cause a major restriction and actually do damge to the filter housing. It cannot handle the volume that we will put to it. The FASS system actually filters 33% better than stock anyways so there is no need other than using the fuel heater in the filter housing which again... is not needed.

On filtering yes, on water separation no.



The stock setup is not restrictive, the stock fitting are. . If you change the fittings you should have plenty of flow.



The OE filter is rated for the same or more flow than the AD filters. . The FASS filters are rated for a TON of flow, but you still get enough flow out of the OE filter (60GPH) unless you are making LOTS of hp. .



The FASS with the 150 series filters is the best bet, you can change the f/w sep to a better filter, the HF filters flow a ton and filter very well... and if you want to get 2um absolute you can just add a Cat filter after the FASS... Also you can choose a f/w sep that has a WIF sensor in it, so you don't have to lose that light.



If I were to ever go with a system it would be a FASS 150/95... . But personally I already have 3 filters and if my LP ever takes a dump I'll just get a stand alone LP.



To the OP... you don't need 30psi. . I would stay with the 12-16 kit.
