4040 is what I was looking at. As long as it is transparent I don't mind. It won't stay yellow with the oil running through it, and the pvc will go yellow anyway. Might be the go then. I am thinking 3mm for the oil lines and 6mm for the feed line. I still have to work it out but that seems the best, I have 4mm pvc on there at the moment and I am worried that the flow will be to weak from the pump.
I am starting to look at how to mount the seat, this will be my first cafe style mount. I am going to try and use the original mounts and lock point. My plan was to create a base plate for the seat to mount on and for the hinges to attach to. I will use spaces to give the seat an even height above the frame.
Anyway back to the garage!
