have you ever owned one or are you going by a what you hear from the internet thing. i LOVE my airdog 2 and i probably wont ever have a mechanical lift pump again. and never once has it given me a problem

 

I have to agree with the Airdog being extremely good and reliable. Put a DF-165 of my friends '08 6.7 Cummins, and it has given him about 1-1.5 MPG increase.

HOWEVER, yes you can hook them up wrong! While I was mounting the pump, he was hooking lines up to the CP3. Stupid truck wouldn't start for a day (would run about 3-30 seconds and then die) but it was because he'd hooked the CP3 inlet line from the Airdog II to the CP3's return line. Yeah, that was a major dumb-butt thing on his part, but we should have caught it before an entire day went by! Talk about dropping your fuel mileage! It went to ZERO until we figured it out! Hehehe

As soon as I can scare up the funds, I will be getting myself an Airdog II 165. Along with a fuel pump pressure gauge to keep an eye on things.

Oh, don't get me wrong, I know what you mean by froggy! I romped the pants off of a vet last summer heading out of Fairbanks, AK heading toward North Pole. However, until we hit 103 MPH and he finally passed me, I didn't belch out hardly any black smoke, and that's with the mods on it. I like my diesel fuel combusted, not stirred!

 

I guess that is just around here people prefer the FASS pumps.

 

Ok I definitely will and if it is bad I need to know what to go with hahahahha y'all are making this confusing ! mechanical, airdog, fass, ahhhhh hahaha

 

the fass is the very first original airdog. if you read the family history it will explain the whole story behind it. the fass has stayed the same and the airdog has continued to advance and grow. there is no doubt about it that the airdog is a better unit. they were both designed by the same person

 

Again, check your fuel pressure first.

No matter what these guys tell you, you dont NEED an airdog if you are going to be less than 500 hp.

 

I shall agree to that, you do not NEED a FASS, Airdog, or ANYTHING other than to test your current fuel pressure, see if it is up to snuff, and then replace your pump with whatever floats your canoe if it is not! Even if it IS a replacement stock fuel pump, which is all you really NEED to keep your truck from eating an injector pump. However, just about ANYTHING would be more RELIABLE than a replacement OEM pump. Do we all concure to this?

 

I'm not so sure I do because an oem pump dosn't require elictricity, therfore IMO is more Reliable

 

No, because he has a '95 with a mechanical piston pump, the most reliable, long lasting fuel pump ever installed on a diesel engine, bar none. The only reason they wear out nowadays is the crappy fuel they are being subjected to. Even so, they still outlast any electric.

 

Wasn't thinking of a mechanical one, haven't ever had to bomb anything but a Common Rail Cummins. Good point, though.

And stop ganging up on me, I'm about to cry over here!!!
