Man, you had to dig deep to find this
!
Thanx, this was my first attempt to wc'ing, and it still lives (had several block changes, but rest is the same)
I used two diff dia hoses, on the pump inlet is 16 mm ID tube (it was easier to stretch the hose on the pump inlet that is 19 mm OD), and the rest of the system is 12 mm ID. I actually managed to heat and stretch 12 mm ID pvc tubing on the inlet, but it looked...at least not nice, nor safe.
I got some more pics, what part exactly are you interested in?
Welcome to the forums!
Cheers!
