My equipment's fuel lines and squeezy bulbs are deteriorating at an alarming rate. While I try to use 100LL Avgas when I can, I can't do it all the time. Last week I changed the fuel line and squeezy bulb on my blower. This week, the Oregon yellow OPE fuel line I installed was rock hard and leaking at the tank. I'm 100% certain that ethanol is causing the problems. When I use 100LL, the equipment's fuel lines and bulbs last for years. 1 week lifespan! That's really bad. Any suggestions? Tygon tubing? Brands? Where to source? etc.
