Your local oreilly's or autozone carry the actron kit.
You can borrow it on the loan a tool program.
The kit does have the correct fitting for the CSI banjo.
A couple points to watch out for.
The copper washers in the kit suck. They will leak at a moderate tightening of teh banjo bolt.
The banjo fitting is cheap chinese aluminum.
If you try to tighten it a little more to stop the leak, it WILL shear...really at a very low torque.
Hylomar does a good job of temporarily sealing your old crush washers (maybe even the crappy copper ones in the kit).
So, get a new set of crush washers from the dealer....they will charge you $2-3 apiece.... which is too high, but still this is likely to be one of your cheapest dealer parts bills.
Use your old washers, optionally with a light smear of hylomar, when attaching the banjo adapter fitting.
DO NOT OVERTIGHTEN...if you do you will be returning the autozone kit and borrowing the oreilly kit...ahem.
Look at your FSM for values and test procedures for the pump and pressure regulator.
Don;t take the gauge as gospel...it is a chinese gauge. Look for trends and basic information. If it says 40 psi...it might be 40, 38, 42 or some other pressure altogether.
The above holds true of most affordable instruments.
Lastly, if you want to purchase your own pressure tester...
I oddly enough yesterday placed an offer of $40 on one of these and the seller accepted.
I've been casually looking for a little while, and don;t think you can get a much better deal.
