Q: Can you use this hose over barbed fittings with high quality standard hose clamps (worm gear)? I have all barbed fittings on my Rotax 912 ULS installation and wanted to use better than standard oil cooler line.

You should avoid using barbed fittings, especially on fuel lines. Barbed fittings tend to contaminate the hose, this can be a bad situation on your Rotax motor since there is not a filter between the pump and carburetors. As usual you should check your float bowls for contamination for the first 10-15 hours after replacing any fuel hoses. As far as if you can use worm drive clamps on Aeroquip 601 hose, no you cannot. Aeroquip 601 hose is designed to be used with 816 fittings. The best option for your Rotax motor is to use Super-Flex hose, clamped with Band-It clamps and covered with firesleeve.
