Airdog 100, 150, 165?

[brunok]

which one would i need to support about 600hp for now and maybe up to 800 in the future? or any other pump recommendation?

I was looking at Kennedy but for the price and filter combo Airdog seems better...

I think that the AirDog 150 is the best bang for the buck. It has the same 150 gph pump as the AirDog II 165. The selling points of the 165 are that it is "easier to install" and has an adjustable pressure regulator. To install it you can do it without lifting the bed or dropping the tank because it doesn't have a draw straw. However with the new quick connect style AirDog 150s you can easily install them without the draw straw if you choose, and if you choose to do so on either you run the risk of sucking the fuel basket in the tank dry faster than what fuel can get into it at low tank levels - making the truck hard to start and hurting performance when you are low on fuel. For the 165 the remedy is to remove the tank or bed and pull the sending unit to drill holes in it so it can fill faster, so there goes the "easier installation". The adjustable pressure regulator is supposed to come preset at the same 9-12 PSI that the AirDog 150 comes with. If you adjust it too much higher it will start to cause idle issues, so what's the point of having it adjustable.

I had an AirDog 150 on my truck installed per the instructions during my 10 second passes - I think it will be plenty of fuel for your 600-800 rwhp goals.

I can tell you how much better it is to have the draw straw,when i installed my airdog 150 i got the draw straw with the kit i bought so i said what the hell and put it in,when efi was installed in my truck it was the same as the hot +2 eliminator on setting 10 the 425 h.p. tune and we had to take the fuse out as the key had to stay on.well we forgot to put the fuse back in but my truck never missed a beat,we tested it on every tune hard and i was on it hard on the way home and i never lost fuel pressure and the cp3 had to suck thru the pump that wasnt pumping!!! Put the draw straw in

I have a ADII-165, I like the adjustable feature, I did not use the draw straw, I did drill the cup.

I just got fuel, 33.22 gallons in a 34 gallon tank and had no issues whatsoever with fuel starvation.

With the draw straw you screw yourself once the tank level gets low, forget about running down to almost empty.

As far as install, if you have to raise the bed it is way easier than dropping the tank.

Sorry for the off topic, but where are yall drilling the cup? Around the base? Would a billet pickup be adequate?

I will respectively disagree I installed the draw straw and have run my truck within a 1/2 gallon of empty without issue. Also it takes 10minutes to drop the tank and you dont need a extra set of hands like you will if you pull your bed, JMHO.. Heres a pic of how I cut some slots on the draw straw...

I did the Hellman sump instead of the draw straw with the AD150 on my truck so I wouldn't have to worry about the 1/4 tank issues. Worked great and was pretty easy to install.

I totally agree,i used my motor cycle lift and some blocks it was easy and i 45 degreed my pick up and have run the truck very low and never any issuses.

I just install them without dropping the tank. I don't see the need. I've never had a problem with the lift pump holding pressure with the stock pickup.

Like Custom8726 I have to disagree as well. IMO the "1/4 tank issues" are the cause of one of 3 things:

1. People cut the straw too short so it is not close enough to the bottom of the tank.
2. People bend the float arm while removing the stock sending unit - bending it down would mean that it would hit the tank bottom before it came to the end of it's travel, throwing off the gauge so that it shows you have fuel when you are actually empty.
3. People cut the straw the right length or a touch long but don't notch the end as Custom8726 shows.

I have had to drive over an hour with the low fuel light on in my truck to find a station that had fuel; when I filled up my 26 gallon tank it took just over 25 gallons.

I'm not saying that there is anything wrong with the AD II pumps, only that the extra cost is not warranted in my opinion. A new spring will adjust the pressure in the AirDog 150.

The only kit that comes with the draw straw is the 150. The DF165 hooks right to the top of your stock sending unit like the 100. The 165 has dual inlet ports to allow more fuel to enter the gerotor thus pushing more fuel, also the DF or demand flow means that not as much fuel is returned to the tank, the ADII has a different base that recycles the unused fuel back through the filters to be filtered again and reused. This way the filters will have more of a capacity and less chance of draining them.

Some trucks that need the extra fuel capacity for heavy fueling motors (like the cummins killer truck) we will run an FPII class 8 unit, this will usually double the fuel capacity and eliminate any fuel recovery issues.

Parking on a hill with low fuel and a draw straw is a recipe for a no-start or a stall condition.

The purpose of the factory fuel cup is so that the fuel is pulled from/returned to the same location.

I am not trying to start an argument over this, just pointing out that not everyone lives in flat land and not everyone parks on a flat driveway.

I have been in trucks tuning them that run with small amounts of fuel and when then accelerate the fuel goes to the back of the tank and starves the truck for fuel.

To each their own I guess.

As far as changing a spring, it is far easier to loosen a jam nut and turn a adjustment then dick around changing a spring to save a few $$$$,

JMHO.

Tony, i most certainly agree with you. Parking on a hill 90 percent of the trucks life i had too go with the Airdog 2, i have no modifications too the fuel cup. I like running my tank down too a half gallon and have no issues on a moderate incline. Airdog 2 gets my vote!
