I agree the plastic clamps are near useless, I will be replacing them with steel. Great idea with the aluminum fuel line, never even crossed my mind. I will plan to make the change if I ever get caught up with my other projects. For now I prefer the urethane over the neoprene for this application. I have a coil of urethane and replace the line each spring.

OR someone in the past recommended using 4 or 5 wraps with tie wire, the center few wraps would create very even pressure between the hose and fitting. boyd young mkiii utah >>>>>>>>>>> -----Original Message----- From: Ducati SS Sent: Tuesday, January 21, 2014 8:20 AM Subject: Kolb-List: Re: Kolbd deatil photos Thanks to all Yes I had help, but after all her time and effort to post the photos I an not about to complain.
