what ID u use? i heard if use 7/16 with 1/2 fittings dont have to use clamp since its tight already.
those plastic tube clamps cost how much? i think i saw somewhere that thing cost around rm7 each

i'm planning to reroute my tube. this is my current setup


bellow is roughly my drawings


on the left is the pump at the bottom, 2 90 degree fittings need to use (i only have 1 currently)
on the right i think need to use 5 90 degree fittings
