Not seen clear pink. I have tried several neoprene tubes in the last year but they all go hard. I spoke to a guy at a Yamaha club and he said they use a yellow transparent tubing from Yamaha. I have been testing the Tygon F-4040-A yellow fuel tubing and it seems very good. It has not gone hard and has shown only very slight swelling. I bought the 6.4mm ID tubing which has a wall thickness of approximately 1.5mm. The only downside is it is not pink.
