What type of plastic tubing can I use for the brake supply lines that will not be effected by brake fluid.

I am not sure on type of hose, but a lot of the vendors sell them. Check with the brake man at PMB.

the ones you have should be good to reuse and just buy new "blue" line connecting hose. If yours are broken or missing, then you should buy the originals as they are specially bent. We have new and used available
