Where can I get some replacement silicone tubing for the Brinsea octagon 20 advance?

The tubing on their website is $2 a foot plus shipping!!!

Is there any way to get that same type of tubing for a better price?

I've found similar tubing in aquarium pet stores that works for the two long pieces, I have been afraid to use anything except their tubing for the one in the middle that goes around the metal thing because of the tension issue and that it might burn out the pump if not exactly right.
