That is if you plug 5/8" into 1/2" barb. But it's a real pain to go that route. You need lots of planning and measurement. You need to make sure the twist is perfect. Because once you plugged it in, you really cannot remove it without cutting the tube and splicing it. Which means the whole tube goes to waste.

Heat gun...

can i ask where to buy heatgun in lyn?

How about 1/2"? So the best for tubing is 5/8" right

just make sure the res must be located b4 the pump
the other are up to ur preferences (depend on ur casing,WBs and other)

anyway guys u can see in my previous post the tubes r cloudy
some are with pink cloud and some with yellowish 'finishing'
decide to clean it
"bathtub + scrub"



i scrub the inner tube using long screw driver wrapped with soft cloth
soaked it in detergent + tap water mixture for 5-10 minutes
then using the same screw i scrub it using car wax ..... hahaha   
soak it inside the detergent mixture again and clean it with plain water
dried it under ceiling fan

and i save few hundred bucks
no need to buy new tube since the guys were out of tygon r3603 already
     

@babun_lapar - around RM1k++
anyway new experimento

soften and straighten the tube by dipping it in hot water



the good side r the tube became more soft and easy tho bend again and the tube oso in straight form

the bad side is by dipping it for a long time will make the tube look a bit cloudy ( translucent ).
few minutes (1 minutes perhaps) is more than enough to soften it

hahaha still developing my own save budget lumi
here the proper way to do it
