I used 1/2" CPVC pipe + some 90 degree fittings to make a DIY spraybar for my 2262.
To connect to the Eheim output hose (16mm or 5/8") I bought a garden hose repair fitting (female to barb) that fits on the hose > 3/4" CVPC pipe nipple > 3/4" CPVC slip x female swivel 90 >short length of 3/4" CPVC pipe > 3/4" CPVC slip elbow > 3/4" x 1/2" CPVC reducer to connect to the spray bar. (The 3/4" swivel 90, short pipe and slip elbow allows the contraption to fit over the tank trim nicely.) I really wish I had taken a picture of my DIY but I didn't because it is a very easy project and much simpler than my description above.
For what it's worth, 1/2" CPVC pipe will fit inside the output hose but will require a worm gear hose clamp to secure it.
If you're very into DIY, you could bend your own J-tube using PVC or CPVC pipe, a heat gun and sand to fill the pipe (cap the pipe ends) to avoid crimping it. I used a soup can as a form to bend to the shape I needed. I've used this method for regular PVC to make my own intake pipe for the 2262 filter.
