It's possible. It's also possible I tossed it on accident. I'm normally pretty good about digging all around in boxes to make sure, but I can't say positively or not this time. I ordered in December. I've ordered so much stuff in the last few months I don't think I have the original packaging anymore. At this point, all I have is the RODI unit and the box with the instructions and accessories. For the price of tubing, I'm certainly not going to sweat it. I have to run it 30ft anyways. Does it sound like the only item I am missing was tubing?
