Fuel does not push uphill, like any liquid and all fuel systems on these are gravity fed from the gas tank.

Just remember liquid will seek it's own level and it will flow "up hill" it the input is above the output.
But I agree it is best to have a downward slope from tank to carb, but if it it not possible it will still flow liquid.
The higher the tank in relation to the carb the better the flow, ---within reason.
