What kind of pump for my ST G90 should i use. i will be flying 3D so it will need fuel flow at every attitude.

thanks, james

If the tank is in the stock location which on most planes is right behind the firewall, you should not need a pump. We will need a bit more information to help you better. Plane, proposed tank location, is the engine inverted sideways or upright, etc...

the plane is a GP extra 300. the tank is located right on the CG of the wing and above the carb, so there is a long way for the fuel to travel. and the engine is mounted sideways. I am thinking about using the perry pump reg.
