Mr.Bob speaks…
I hate to disappoint you guys, but I emailed Bob to let him know of your interest and here is what he had to say, "I can't consider it until the 3rd gen sets are completed. "
I also emailed HighTempSilicone again and asked "So, you could make the lower radiator hose-which has one bend–but not the upper-which has multiple bends-right?" They replied, "I would have to see the hose. If we can make it, we would need to make a tool. The prices of tools are pretty expensive. "
If anyone has precise measurements for these hoses, maybe we could use them to get a batch of silicone ones made.
So, no luck yet. I'll keep at 'em and post a thread when I have some luck. Until then, I guess we'd better go with the rubber hoses. PDR, are you listening?
