Best way to replace a turbo's return line o-ring

[SleepyMSP]

It sucks but I never got the chance to change the o-ring it has either been raining or too dark for me to do anything, I will probably get to it this weekend as I will have access to a garage to get the work done

Well I might try the trial and error myself. O rings should be cheap. What general size should I try to stick around?

My little allen bolt was so damn tight on that bracket for the feed line, of course it stripped, so i took a cutting wheel to it across the bolt head, got it out with a flathead screwdriver....... The fitting to the turbo comes on and off nicely with a crow's foot. Return line is on the bottom and very accesable from under the car.
