: what size are the return lines on a 6.2?

I need to instal a temp sensor on the return lines as close to the injectors as possible because i am running on heated vegetable oil and need to know how hot it gets as it goes through the injectors.
On my system the injectors all have a very thin hose that links them all togethers, looks like 1/8" but i am not sure, then there is also the return line from the injector pump that comes right out the top; and then this line as well as all the lines from the injectors connect to a steel line. Unfortunately this is probably the best place to instal the sensor but it is a steel line and would not be easy to do so, unless i know the exact size then i may be able to do something with compression fittings.
Can anyone tell me what size these lines are - both the hoses from the injectors and this steel line?
thanks,
Paul
