Pumps always like to operate against what is known as 'head'. The more the
better, within its limits, as far as the pump is concerned. 'Head' is
determined by the distance the pump has to thrust the liquid. Therefore, it
is always best to place the pump close to the source of the liquid; ie: the
reservoir tanks. This will allow the pump to operate against the required
head pressure and even out the pulsing of the fluid as it is evacuated from
the fuel line.
Put the pump in the back. My friend's Alpha has a pump in the tank.
It may cause some vibration anyway and you can always pass it off as a
muffler rattle.
