Can this be put into an injector cleaning system pressure cylinder and engine runs directly off this chemical or does it have to be blended with gas?

Mix 16oz bottle with 64oz (1/2 gal.) of diesel. Run directly into fuel lines on top of engine. Make sure to include the return line to your cylinder. My 02 Duramax took over 1 1/2 hrs to burn thru mixture. DO NOT put the cleaner in your fuel tank!!! Works great!

Can you use this to put directly into the cylinder to free piston rings? If so, how should it be used? How much, how long, etc.

Spray some WD- 40 into cylinder to free up piston.

Can I put this in the crankcase?

this product is for cleaning fuel system not the oil system I would NOT put in crankcase

?The product show is no longer avalible under this part number its now sold as 19355198 it has new packaging and pricing old stock is still ok

Do not know about this. I do know the Genuine GM Fluid 88861803 superseded the 88861802, and I have not sought out any lately as I have two bottles of the 1803 left from several I bought.
