In the past I used a transparent hose of a hose, but it cured immediately and leaked out. Click here for somewhat higher value but purchase as it will be okay as it is oil resistant.
Although I can not see the effect at the moment, how much do I have?
The hose of the gear oil pump for Perekan became hard and the handling was not good so I changed it to this hose. I do not think there will be any problem at the moment, but I will exchange it again if it gets harder.
