I am getting ready to buy an AirDog 150 fuel system for my truck. Is the AirDog II worth the extra $100 bucks? What are the pros of the airdog II? Their adds say you don't have to remove the tank, but to look at their pictures it looks like it comes with what looks like a sending unit. Never installed a pump before, any comments would be appreciated.

 

It does not come with a new sending unit but it does come with a kit to upgrade your existing sending unit. You must drop the tank or remove the bed, your choice.

 

I believe it would be just as easy to remove the bed, I guess. What does everyone else do? What is easier?

 

Removing the bed is easier from what I've read. On my truck though for the AD100 the tank didn't have to be touched besides to hook up the fuel lines from the quick connects.

But on your truck the bed will have to come off.

 

i dropped my tank because i had to clean it when i installed my airdog and it was actually pretty easy. i think its 15mm deep socket for the tank straps, and i just disconnected the back part of the driveshaft.

 

I also dropped my tank. Much easier in my opinion if its semi-empty.

Ive had my bed ff twice. VERY easy, as long as you have some sort of help, either a few friends or a place to hoist it with a pulley and come-a-long. Harnesses drop quickly after removing the tail lights. And dont forget the ground strap from the bd to the cab (I did that last time, oops). But if you are going to drop the tank, rig a stand for your jack and try to make he tank as empty as possible.

 

I would also pull the bed. I have pulled mine 3 times now and we just set it in the lawn while working on the truck. Is the ad II worth the extra hundred? No clue.

 

I took the bed off because to me it easier to install the drawstraw with the tank still mounted instead of messing with it out on the ground. some type of crane or engine hoist would be ideal to pick it up with

 

I personally did not find the Airdog II to be worth the extra $ but then again, I'm a cheap bastard.

I drop the tank b/c I have a very full toolbox and usually misc junk in my bed. I've dropped it more times than I care to remember and have found that if you use a couple of cinch straps (not ratchet) to support the tank it makes it much much easier to raise and lower the tank. By using this method, I was able to drop and reinstall the tank w/ nearly a half tank of fuel.

 

Take your tank off and install it with a 1/4 tank if possible. That way everything is in it's natural hanging state. Dropping the tank usually allows the tank to "NOT BOW" and then when you have a 1/4 tank, you will cause it to run out of fuel. Just my observations seeing I have installed quite a few of these and the FASS kits too. 1/4 tank issues suck...

 

Ahah!! There it is folks!

Reason to pull the bed off as opposed to drop the tank is to keep the tank in its installed position for the drawstraw. The drawstraw installation is key, it cannot suction to the bottom of the tank. A good idea when installing the straw is to bevel the bottom of it so that it will always allow fuel through.

 

Well according to air dog the AD2 is supposed to get rid of the 1/4 tank issues. That is why I asked if the AD2 is worth the $100. Does anyone here have an AD2? And how does it eliminate the 1/4 tank issues?

 

If you install the straw with the tank bottom flat, you will have 1/4 issues.

I have done it both ways, taking the bed off is much better/easier in my opinion.

 

I understand the 1/4 tanks issues. But if I get the ADII will I have to worry about it?
