So I just finished my savage xl mid tank mod with the ofna 250cc 1/7th scale tank and new fuel line. When I started it for the first time today, it ran good with a full tank, but after it got a bit below half tank it began to idle funny as if it still had the half tank lean problem. When I checked the fuel line, there were large air bubbles in it, almost like gaps of air between fuel. The tank and fuel line are new and I never had this problem with my old tank and set up. Any ideas what it could be or how i could fix it?

Thanks
