Be careful talking the bolt off the back or you'll strip that allen head, you'll be like me having to use a torque head to get it out.

 

Your signature says you have an AD2 already... why are you putting this on even?

 

Because they do 2 different things...

Maybe Doug can chime in here.

I've been putting on aftermarket pumps like the A1000's with a regulator kit. I feed the front with 90* fittings and return from the rear with banjo bolts that adapt to pushloc and go into an aeromotive regulator and then back to the tank.

 

I was curious why you would even need a RR with a AD2.

 

Maybe I should reword this Wouldnt the regulator on the airdog cancel out the regulator on the RR kit? Why would you regulate it twice?

 

Because they do 2 different things...

 

AD2 still doesnt open the back of the heads, its why I went with what I did. Airdog 150 with a RR

 

Would a crossover be just as good?

 

Im pretty new to the game and still am learning but as rescueF250 said by installing this kit it opens up the back of the heads. Thats what i was told the one bolt not so bad but the other a real pain, about how long did it take to install.

 

The rear are pretty easy, you probably need an extra set of hands to make it go through easy, fronts are the worse part getting around the hoses n belt that will take u the longest so give urself at least a day or two in case you run into any problems.

 

If you put that on, whichever system is set at a lower pressure will be doing all the work, so if your RR is set at 65psi and your AD2 at 60psi, the airdog is doing all the work and the RR is doing nothing (other than making a cross over for the back of the head), and vice versa.

The rear bolts are always a PITA, they've been a PITA for me when I've done vegistroke installs.

Do you have dual alternators on your truck? That makes getting to the front bolts a PITA! I know because I have them...

 

No his truck has a single alternator setup. He bought my old truck and i never installed it so i would think instead of collecting dust he mise well put it on it won't hurt anything correct?

 

You don't need to regulate it twice.
You don't really need a pump that has a regulator with the RR set-up, but if you do then you would want to set the pump at the higher pressure (lets say 70-80 psi or at the max), then set the required fuel pressure with the RR kit regulator.
