Fit near the tank, below fuel level if possible, with an inline fuel filter before the pump, and wire it from the ignition-switched supply (terminal 15). A fuel cut-off / inertia switch is recommended. Replace the old fuel filter when fitting.Questions? Contact us with your vehicle, engine and carburettor and we will help you choose the right pump.
