Hello,

I have a ST 2300 mounted on it's side with a bisson pitts muffler one pipe plugged. This is mounted on a 1/4 scale cub and the location of the tank is centerline about 1 1/4" below the center of the carb. When trying to prime the engine, fuel will not reach the carb. A few drops will come up the fuel line but, will run back to the tank when taking your finger off of the carb. The tank has been replumbed. Would a fuel regulating system or fuel pump be in order here?
Thanks,
jc

If you can't get your fuel tank higher, so that the centerline of the tank is no more than 3/8" or so lower than the center of the carb, then we would suggest a pump or pressure/regulator system. The fact that the tank's so low is the source of your fuel feed difficulties.
