Recently swapped a 2003 700 skidoo motor into a 670 chassis but not sure wich line from oil tank goes to wich fitting on the motor right now I have it connected to the the fitting on the clutch side of the motor is this correct or do I need to make a change?

The fitting on the PTO side is for the factory fill of Isoflex grease for the PTO bearings and is now a vent. Do not use it. The 700 is not a rotary valve motor like the 670 and doesn't have a return line from the auxiliary shaft cavity in the crankcase. You will need to cap the original return line or use a injection oil reservoir fro a CK chassis.

There is three fittiings on the case the one close to the pto is capped but the next one is a .straight fitting and is hooked to the tank. and the next one is hooked to the fuel pump ? Is this correct and do I have to change oil resevoir. I have capped the bottom line on the oil tank of course not the line to the oil pump

Just make sure you have the lower aux shaft feed line connected to the fitting in the middle between the cylinders. The Series III engines don't have a return line. No you don't have to replace the reservoir but it makes things simpler
