List
I am getting ready to do my 5th. "Conditional" and I am going to change out the fuel lines again.
I am planning on using the new Parker Super Flex FL line as sold by ACS.
Can anyone recommend this fuel line or any other / better ?? I need one that can stand up to Ethanol even though I am currently not using it. I am using Marine ( Non-ethanol ) fuel rated at 92 octane and boosting it to 93 octane. It is working great and I have not noticed any change in performance or temps from the 100LL.
Also does anyone know of a small hose clamp ( and source ) that will work on the connection to the carb. The clamps I am using are about 1/2" wide and cover the bead on the metal line from the carb. I would like to clamp it on the small tube prior to the bead if possible. Is anyone using the spring type automotive clamp?

Any info would be appreciated

Bobby, I'm no expert on Jabiru engines but I have had good luck with Oteker Ear Clamps. They are a single use clamp so you have to have several on hand but they seem to hold much better than worm gear style clamps. A side benifit is the "ears" don't stick out as far as compaired to the screw on a worm gear style clamp. If your interested in seeing more about ear clamps, the EAA has a video about them in their homebuilder hints section.

I am using Parker Superflex on my Rans S-6S after Rans issued an AD to replace all the blue flexline.
Works great for me with AVGAS, Euro95 and Euro98 with and without Ethanol.

You should be using a good band clamp on the fuel lines like the Oetiker band clamps. These are usually the one eared pinch type clamp and easy to use. The serrated worm drive clamps you can get from the hardware store really aren't acceptable. At the very least they should be fuel injection clamps which are a screw style clamp, but can't slip as the have a nut and screw and apply good 360 circumferential pressure around the fitting. These can be puirchased from any auto supply house.
All fuel lines should be in fire sleeve and a band clamp like a Band-It clamp used on them. The ends of the fire sleeve can either be dipped in "End Dip" or can be wrapped with fire sleeve self vulcanizing tape that has a fire rating like the fire sleeve it self.

Gaggle:

There is only one worm gear hose clamp that is approved - Uh-oh!  APPROVED!  Yes, sometimes one should use approved items; only because they were tested and have a good history.  Well, the item is made by BREEZE EASTERN.  It is a very good quality hose clamp that does not deform on the band and the wrapping is uniform all around; it is used by the military and GA.  These items are NOT automotive and defiantly NOT Chinese.
