If you intend to install an electric fuel pump, I strongly recommend you install it as close to the fuel tank(supply) as possible. Electric pumps are a lot more effective as a propulsion(pusher) rather than suction(puller).
Facet makes the little square one for aircraft with pressure under 2 psi, web shop you should be able to find it for under 30, mount it on rubber pedestals to quiet the noise(making sure that you supply a ground wire around the mount from the body of the pump to the chassis).
