what fuel lines/ hoses are you using on carb motors ?

fuel pump sends it straight through, only pump the rubber fuel bulb as per normal, you will hear it going into the carbs, then bulb will go hard .

Tygon is so soft and easy to work with and being clear is nice for diagnosing air leaks and such. It's obviously not nearly as durable as proper fuel hose... My question. IF you did use Tygon for inside the cowl fuel lines, how long could we expect it to last? 10 hours? 100 hours? Something in between? I'm tempted to try it on one of my motors just to see.

You can, but sometimes its tricky. You need to make a clean cut. There is usually a white liner in it. If you try to stretch it over a larger barb, the liner will roll backwards into the fuel flow passage. Its for high pressure so if it says its for 3/16" it don't really like to go on 1/4". If your always removing and installing the same hose, the liner gets loose at the very end. Its fantastic stuff, but as far as for me. Its not the greatest for a lot of removals. I pull hoses all the time, if it were a once a year hose pulling job, Id probably buy it. But not with my stuff.
