Help!!!

I need to install a 4-stroke Magnum engine (.30) in the upright position because sideways or upsidedown, the engine will foul the steerable front wheel. However, this will put the fuel nipple and the high speed needle valve about 1" above the center line of the fuel tank. Will I be able to get enough fuel pressure to run the engine in this position.

I am going to use the pressure nipple from the muffler to pressurize the tank as well as the pressure nipple on the back plate of the engine. Is this too much? Can I use both of these fittings at once. The instructions which came with the engine did not even acknowledge the pressure fitting on the back plate. That is designed to ptovide pressure to the fuel tank...right????

Hope to hear from someone...Thanks...Mike
