Most of you who are FI do your own maintenance and will find this thread to be a repeat but for those who are new to the FI scene and the Comptech setup, this DIY will help you to do your own oil changes and work with the Comptech oil return line fitting.
1. Remove the oil return line from the oil pan by using the crescent wrench to freeze the nut closest to the pan. Using the 22mm wrench, hold the crescent wrench steady and turn the 22mm wrench counter clockwise till it loosens freely. At this point you will be able to hand loosen the fitting.
2. Pull line away from drain fitting and drain oil into pan. Make sure to not manipulate the line too much as it will possibly loosen the fitting on the blower.
3. Remove oil filter using oil filter removal tool
4. Replace oil filter after applying a light coat of oil around the rim of the rubber gasket.
5. Tighten with oil filter wrench.
6. Attach oil return line to drain fitting and tighten.
7. Add oil to engine approximately 5.1 quarts. With the addition of the Supercharger you may need to add a little more oil. This is why you must check to oil level line on the dipstick to make sure you have the correct amount.
8. Once levels are good, replace oil cap, replace dip stick
someone should design a t fitting for the comptech s/c. that way you can run the oil return without having to remove it every oil change. screw it into the block,oil return on one side and stock plug/fumoto on the other.
I hear people say they hate the Vortech because the oilpan has to be tapped. Now, I see people complain about having to fiddle with a Comptech return line on the oil drain. I guess it's true. You can't please all people all the time.

I hate tapping the pan because it leaks at least mine did before I had to get the mofo fixed.
I think the fittings are 7/8" (slightly smaller than 22mm). That's what I use. When I tried my 22mm is was slightly too big, and being aluminum, strips very easily.

Great pictorial write-up!
Thanks for your input..
I've heard this too and I've found that the fitting that turns counter clockwise will fit inside a 22mm wrench. The fitting against the oil pan will not. This is the reason I sometimes have to use a crescent wrench.
The picture I posted was of 2 22mm wrenches that fit....
I guess what ever you have that works at the time.... I was more concerned with showing how to loosen the fitting without ruining it...
