I am contemplating on either the 100 or the 150 Air Dog pump and wanted to get some opinions. As you can see in my signature I don't have much done to it and probably the only other items I am going to get are 150HP injectors and a new trans (when I blow this one out). I know most of the time the saying is bigger is better but I have heard different things on this subject.

Thanks

 

i went with the 100 so that i would not have to put the different drawstraw in(seemed like a pain and i didnt want the chance of having the 1/4 tank problem that some are having).....i cant pull it down below about 13 but i don't have extensive mods haha....but installation was pretty easy....

 

Go 150, more is better when it comes to fuel flow. Whatever fuel your engine doesn't use just routes back to the tank. You don't have to install the draw tube in the tank.

 

is it still 150 if you dont put in the straw? figured that would pull it down some...

 

A few guys installed them & later installed the straw. They said they saw no difference between stock/draw tube as far as performance or fuel pressure.

 

well in that case i have to agree with j lent, go with the 150......either way you will be happy.....i love mine, and with the 150 you have room to play and grow

 

if i would have known there was no difference i would have gotten the 150 haha....whats your psi at idle jlent?

 

I stretched my spring. I have 24psi idle.

 

go with the 150 it is a no brainer.

 

I figured I would go with the 150 because I noticed it has a return for air and unused fuel.

I think I'm just going to bite the bullet and install the straw because I am going to be under there anyway.

 

that is probably what i would do if i could do it over again, J Lent, where is the spring you stretched? is it on the 100?

 

The fuel tank is actually really simple to drop, don't know why guys don't do the straw? You'll be better off. When I dropped mine, the stock suction line was rusted badly.

 

Just remove the return line & fitting from the airdog, spring is right behind the fitting. Not sure if 100 has it?
