Thanks for the response. That information is very helpful. I am using bubble less tanks on my four engine trainer kit bash. I was told that with four engines all vibrating at the same time. I was going to get foaming in my tanks, unless I padded the tanks very well, or used bubble less tanks. I found that the bubble less tanks took up less room. Thanks for the tip about pinching off the line to the carb. Guess I'm going to need 4 small hemostats. Is it bad to use a push type refueling probe with a bubble less tank? Thanks again!
