aftermarket fuel pumps

strokin6L · Apr 7, 2015

How many guys are running aftermarket fuel pumps on their 6.7's? Brand and flow rate? Pros and cons? I know Rich (UNBROKEN) is running an airdogII 4G and seems to like it. Just wondering what else is out there. Buddy has a 2014 with her delete, 4" exhaust, no limit intake and H&S minimax. He's looking to maybe get a fuel pump for it.

Here's my very non-scientific observation.
Before the added pump at WOT it would haze out the exhaust through 3rd....maybe part of 4th gear then clean up. After the pump it'll haze all the way through every gear.
Is that normal? I dunno...I only have one truck but it's definitely a more solid supply of fuel on my personal truck if what's coming out of the exhaust is any indication.
I didn't check RP at WOT before or after....just posting what I noticed.

I will be doing the H&S kit soon.

Our kit works very well. It supplies 150 gph of fuel to meet your fueling needs, provides excellent filtration and utilizes the best parts on the market. Our kit also includes the fuel filter housing so you can use better, less expensive filters.

Made in the USA

I would have loved to try the H&S kit....but my pricing through AirDog is too good to pass up. Or lack of pricing if you will. LOL

Thanks for the feedback so far guys! Are these aftermarket pumps stand alone or do they piggy back the factory pump?

Mine feeds the factory stuff with 10psi.

I have the same setup as Kaleb. Two OEM pumps.......

Where can I get a price on the new AD II 4G? I checked a few places out, but they only have the AD II 165DF or the AD II 100....not the new 4G pump.

Just found Thoroughbred Diesel sells the AD 4G for $739.

LOL....what would you suggest Mike?

Do the 6.7s really need that much fuel? Two 6.7 pumps has to flow a crazy amount.

But how different is the old AD II 165 from this new AD II 4G?

Our kit replaces the factory pump but uses the factory wiring harness.

The problem with the old pumps as the whole world knows was diesel getting past the pump seals into the motor and shorting them out. The new pumps completely separate the 2 with a whole new drive system. I don't expect any issues whatsoever with the new design.
