I did the ITP RR and Airdog 150 at the same time. The Airdog pushes fuel and utilizes the factory HCFM but still provides plenty of fuel for stock or slightly upgraded injectors. I'm not a big fan of the FASS pumps either, have just heard of too many failures. The airdog and ITP RR combo is a great setup for most street driven trucks. I do plan on adding a raptor pump and getting rid of the HFCM when I get a set of 190's. Be warned though, since you didn't do the RR when you had the cab off for the head studs, the rear return lines are a PITA! If you're not a GREAT mechanic I'd advise enlisting the help or paying someone with the experience to do the job for you... I had a ford master diesel tech install mine, and it took him 4 hours (cab on) and half of that was just fitting the 2 return lines at the back of the heads. If you do it yourself with a buddy, plan on an all day job...
At the time the purchase of the studs was cutting deeply into funds. Most of my money goes to my monthly payment and fuel to drive it! haha.
I can install it myself. I've done a vegistroke install myself so I know what I'm getting myself into with those fuel lines on the back of the motor. Frustrating for sure, but doable.
I'm all about trying to learn as much as I can with these trucks. This is my first diesel and I'm learning as I go, but at the end of the day its all nuts and bolts like everything else I wrench on!
Its funny you guys mention the Airdog, because if anything that is probably what I'll get (despite my thread title). My parts guy always sells those over the FASS pumps, and he's recommended the airdog to me.
OK anyways, at this time I'm not really planning for injectors. I mean maybe later, but not for at least a year. I'm just thinking in order of what mods need to be done when the day does come. So if you had to buy one before the other, would you get the airdog or the ITP RR? Why one over the other, or should they both definitely be done in conjunction with each other? IF I have to do both at once, I can, but it will take a while longer for me to save that much cahs! haha
Thanks guys, Mike
