I don't think I still have instructions. They'd been copied so many times they were almost unreadable anyways lol. I can tell you exactly how the hose mounts plus I have close-up pics on my build thread. I'll measure hose soon as I can. I don't get home from work til around 8 so not sure if it'll be today or not. I get off at 5:30 tomorrow so I definitely can then. Not sure what size hose is at the ends. I seem to remember the PVC pieces being 2" but I'll check just to be sure. All you need are 2 PVC couplings, a 90, and 2 hose clamps and you'll have everything I got. Plus a couple of cable ties.
