Bypass hose swelling

I can’t find those for the K5’s that I run. That’s why I made my own with the hex plug. But if you can get something that works off the shelf, all the better.

Did you ever figure this out? We just switched over to K1s and are getting swelling from on of our bypass hose. Using 3/8" poly braid on it.

Drop the poly and get a stiff hose such as leftover kuritec or even spa suction hose. K1 doesn’t care about diameter

got it, thanks!

But I’d get atleast 1/2 in hose
