A+ customer service but longevity?

My airdog 200 gph died in 171.4 miles. Just finished a brand new engine build that took me a few years to fund and complete. I had the airdog on the shelf since 2013. I was ready for a lengthy phone call and some begging for an easy solution but much to my surprise a quick 15 minute phone call had a 240 gph motor on its way to me. Truth be told I'm extremely disappointed I'm already replacing the fuel pump that was installed a week ago but I'm glad it's a company that stood behind their product. Wish me luck on the next one.

I might be getting the 4g. After looking for a 240 pump and only finding 200 4g pumps online. Maybe I thought I heard "200-40 pump" but he actually said "200 4g pump".

Well I just received my replacement motor..................
Says it is a df-165-4g. P/n: 901-70-0400-w. Did I just get screwed? They told me the 200 gph isn't enough to keep up with the pressure I was running then they send me a smaller pump?

And they're closed.

It's very possible that they run the same motor on both a 165 and 200. Assuming they both run the same rpm, the pump rotor is what would make the gpm difference.

Update for anyone who ends up in this thread in the future.
I spoke to airdog. They did send me the 165 4g because of my current modest horsepower. I had the 200 gph because I have plans to keep adding but they told me they have had people run the 165 pump over 1000 hp, and the 200 gph would be more likely to burn out running it with such low horsepower. They followed that up by saying if the 165 pump ever becomes too small for my application they will upgrade me free of charge.

Great company!

WTF???????....
Please tell Me you asked them how that could be possible?.I'd LOVE to hear that explanation. No matter if its a 165gph or a 200gph the reason it failed will be the same.

Sending me a pump for what they "thought" I needed vs what I had purchased, is not what I'd consider A+ customer service.
Had they confronted me about it and I ok'd it, it'd be different.

I didn't bother asking the tech help person. I would imagine their thought is pushing 200 gph through a pump that isn't using near that amount of fuel is more of a restriction and therefore the 200 gph is working harder? And I was pissed I was sent a smaller pump without discussing it but if they want to give me free upgrades if I need it in the future and this pump is better suited for my HP level now, I'm not too worried about it.

This pump is definitely different than the old airdog2 pump. Runs silent and no vibration. The old pump I could almost hear over the engine. As long as it lasts I'll be happy.

Well the NEW version 4g motor lasted a mind blowing 958 miles. Left the house running 40 psi 20 miles later 0 psi. Changed the filter. Still 0 psi. What is this crap! Spend $700 for a pump that doesn't last a few months. I don't even drive the truck daily. I'm banging my head against the wall. Where's the 5g pump????

I haven't had much luck either. Went thru 3 of the old style pumps, now on a 165 4g. pressure varies all the time and doesn't hold pressure with a stock pump and small injectors. Hopefully it lasts till my next build then I'm getting a fass

Pressure started to drop to 20 then come back up over the last 100 miles but it's over now. Doesn't even put enough fuel out to start the truck. Can't believe a company can be dishonest enough to keep selling their product that doesn't work. Close your doors or buy good motors it's that simple.

Both brands suck. I ran a stock 12 valve pump on my p-pumped 24v and it never gave me any trouble. You'll always be able to make it home with 12v pump.

Even better, if you have your pump at a pump shop, have them put the mechanical pump on the side of it. Run 2 mechanical lift pumps.

With as much innovation as there is out there, I'm surprised someone hasn't come up with a dual mechanical pump setup using 2 12V pumps. Last for years and put out more fuel than you'd ever need.

Update..... pureflow said they would send me a new motor out. It's been a month... Still no motor. Tried to drive the truck to pick up my motorcycle jack... 5 mile round trip. Well the pump quit completely doesn't turn at all and I'm stuck on the side of the road waiting for a tow truck. Absolutely do not buy airdog fuel pumps!!!

Talked to airdog while I'm walking home in the 95 degree weather. They said yeah we remember saying we would send you one but we didnt. We will send you one today. And for my trouble they said I don't have to go through the hassle of sending the old one back.. lucky me. Once again do not buy an airdog fuel pump, unless you don't plan to ever drive the truck.
