i'd do a holley blue. i've installed them on several trucks, and max time install is like 30 minutes. just two bolts, two wires, and a hose in and out.

 

wish some one would address the Q. How much time will it take to install a Air Dog ..? compared to a stock pump ? thanx

 

That depends, if you have any problems with the draw tube or not. We went round and round with that darn thing. I would plan on the better part of a day to do the install.

 

It took me about 3 or 4 hours to do the Airdog 100. Most of it goes really quick and is very straightforward. The majority of the time was spent: fiddling with, and worrying about breaking, the weird connector on top of the fuel tank that you can barely reach; fitting the fuel hose onto the pushlock fittings (helps to put the fittings in the freezer); and deciding where exactly on the frame rail to mount the unit (I placed mine so it's sort of protected by a skidplate).

I didn't have to pull the bed to install a new pickup in the tank with the 100. The 150 unit requires you do this, and that would make it pretty much an all day job.

Compared to a stock pump? A stock lift pump I could swap in about 45 minutes or less, since I've done it a couple times before. The only hassle with that is really where it's located, helps to have long arms.

So, quite a bit longer to install than a stock pump, but well worth it.
