as a general rule when you put in a aftermarket fuel regulator you put it in the return line....
the kink could be possible acting like a fuel regulator and starveing your engine...fix line and keep fuel lines as far away from exhaust or they will get hot and perculate giveing you same symptoms as a pluged or restricted fuel filter
