As said above, it is a number of small parts that will bolt onto your stock cp3 injection pump that are already modified in such a way as to increase the fuel output of the cp3. Usually, you will also need to upgrade the stock fuel pump (the one in the tank) to keep up with the increased demand.

As far as the pump goes, do some research here. There are a lot of options. Everything from the nice quiet walbro kit that uses your factory fuel filter, to full blown FASS and Air Dogs that have their own filtering, to mechanical mitusa pumps with homemade filtering setups.
All in what you want to do. At the power level that a Arson 3 would support, the smaller end of those choices above would suffice. Just to repeat though, I'm not saying you NEED one of those pumps right now... that can only be deteremined once you have your other stuff in place, have a fuel pressure gauge that you can watch, turn up the power and watch what your fuel pressure does. If it draws down toward zero or something close, then you need the additional fuel pumping capacity. If not, then you are good to go.

Rail pressure gauge?
I have no personal experience with the kit itself, but those who have used it seem to be satisfied with the results.

I just got the Arson III and have spent three days working on it, make sure you have a 1/4 drive (to fit in the tight places) and trq head bits for it. I striped the very bottom trq head bolt on the bottom of the gear motor, thats why I have been playin with it for so long and know can't do anything tell this weekend to fix it, so be carefull with it. But I have herad the end product is awsome from a guy I know with an 04.5.

Yeah the directions tell you which ones you need for each part, the directions are stright forward and easy to understand. The only thing I found on the directions was one part you are told to use a 17MM socket you need to use a 17MM open end wrench.

Yes. You just need to be very carefull and clean. The instructions are very clear about this. There is a check ball that has to be placed back into the hole that it came out of. If this is not done, bye, bye pump.
Don't over think an Arson upgrade. Just do it. It is very simple and takes only a few minutes. The instructions are very clear and there isn't really a whole lot that you can screw up.

I found that when working on the pump it helps a lot to jack up the truck and take off the left front wheel and wheel well. Seems like a lot of work but it's a lot easier to get to it from the side. Just my .02.
