I am ordering a vp44 and was going to replace the stock replacement fuel pump while i am ordering which airdog do yall recommend. i am going to stay stock might install a smarty later on down the road. any suggestion.

ad 150 would be your best bet peace of mind now and down the road when you add the smarty

Yeah, may as well go at least 150. Probably could do the math on fuel return and with some mods a 100 would be insufficiently cooling the VP44. I'm not sure the cost difference, but I doubt it is that great.

Which ever pump yall get, install a fuel pressure gauge with it. You wont be sorry.

Do a 165. That leaves you with the ability to do performance mods without having to up the pump again if you get a 100 or 150. When I got the 165, it was about the same price as a 150. I had to put in the tank mod and all that, but it is worth it.

Rule of thumb...100 GPH is good for stock to about 450-500 HP.150/165 GPH is good for stock to ???? :shrug:I've been running a 150 GPH AirDog now for many years and it done just fine for keep the fuel pressure and the fuel clean...

I put the 165 in mine So would be covered for anything i might want to do later. The pressure regulator is nice and it came with the intank pump kit for about $100 more than the 150 as I recall
