I mounted mine (Holley red) in the left fenderwell behind the left rear tire. I figured it would be noisy in the trunk.
I installed an inline filter between the tank and the pump, and I kept the mechanical pump hooked up, too. I am pushing thru the mechanical pump with the electric.
This has worked well for me. I still need to install an inertia switch (highly recommended) inline with the fuel pump wiring. Because I haven't yet wired in the switch, I normally only use my electric pump for starting or high rpm bursts.
