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

u use car wax to wax ur inner tube? this will reduce the friction so the water flow might be higher too. lol
seriously, car wax is some kind of solvent mixture that can remove dirt. i wonder wat will happen to ur acetal for long term.
i notice ur tygon trademark is missing as well.
