Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.

If kinking the fuel return line seems to make the engine run better I would suspect you have a weak fuel pump . All your doing by kinking the line is increasing the fuel pressure. I would start with installing a fuel pressure gauge to the system and monitoring the fuel pressure while the problem is occurring.
