Fuel pump location

[deezee]

What is the general consensus for the location of the fuel pump? I was going to put in next to the fuel tank, in that unused space behind the wheels. But does a bike carb pump need to be below the outlet? I assume its self priming and therefore it won't matter?

Is there any IVA related into to take into account. I assume as long as the lines are fixed at regular intervals and are in no risk of touching any moving parts, I'm OK? Does the fuel pump need to be fixed on rubber mounts?
