[Help] Yamaha Rx 135, replacing oil tubes.

Hello forum.
this is my first post and my first thread here.

And one thing to know about me, is i like to do things myself :biggrin:

I recently bout a 500ml of Shell VSX 2T oil.
But my bike's oil pump rubber have gone bad leading to oil leakage, in-turn was cutting short the oil supply.

I had bought the replacement rubber tubes for the oil pump. genuine yamaha make and i've decided to replace the tubes myself.

Is there any advice or anything to know if i'm going to replace the tubes myself?

I pretty much have an idea what is to be done. but if an expert here could guide me i would really appreciate the help.

Regards,
Uzayr
