just wondering what sort of $$ i am looking at for rad hosing? i have created all the necessary bends, just need some hose to fill in a couple of straight sections, what sort of grade rad hose should i be using to cover a 1m length and what should it cost me per metre (roughly)
cheers

Water suction hose from Purple Pig Bayswater will cost approx $30 per metre and it wont collapse or suck in, so will work well. Cut with a hacksaw.

cool, cheaper then i expected, hopefully it comes in the right size, thanks peter

38mm ID (inner dimension) is definitley available.

Use real good stainless steel bolt hose clamps.

The hose I got is "green line" called thus because it is black rubber with a green line on the side of it. It has an 80 degree temp rating. That does not mean it melts at 80 degrees. What it means is it is rated to 150psi at 80 degrees. The pressure rating drops as the temperature increases, so at 110 degrees the pressure rating is 130 psi or thereabouts. Seeing as radiator water doesn't really see above 110 and should never see above 15psi, then the hose is rated well above it's intended purpose. Not oil resistant, but again, you shouldn't have oil in your water.

Put it this way, no OEM radiator hose would be as thick, strong, pressure rated or generally tough as this stuff.

You can opt for "red line" suction hose, and it is mining standard and has some serious ratings. Chemical resistant etc. Heaps more expensive though.

The clamps I used were Tridon T-Bolt clamps which are able to squeeze suction hose to a seal without slipping.
