Fuel feeding question
I have an older .60 sized cub which i am installing a Magnum .70 4S in, My question is the fuel inlet on the carb is about 3/4 to 1" above the center of my fuel tank. I cannot raise my tank or lower the engine as the orignal owner set it up with the engine running 90*. what kind of problems will i encounter with the carb inlet being higher than the tank and will i need a pump for this set up? Any idea's???
Thanks..
Thanks..

RE: Fuel feeding question
Yes i am pressurizeing the tank, i also have a perry pump but prefer to save it for another project i'm working on. The last time i ran one with the tank low i had idle problems but i dont know if that was the problem or not. I built a set of floats for this plane but had a "hard" landing with my other plane so i quit this one to repair my P51, Now i'm back on the cub. Thanks

RE: Fuel feeding question
You shouldn't have a problem feeding the engine with the tank being lower. Just means that the needle valve setting will tend to be more open then what it was in a prior aircraft. Do use the pressure feed from the muffler and be aware that if you fly the cub upside down, your engine will tend to go rich.
