Not sure of exact vintage, but we think this one as installed about 2007. Found on an MGA in Calgary, Alberta, Canada in August 2017. It ticks like an SU fueo pump, and stops ticking when pressure is up, but it is electronic and polarity sensitive. The entire body and structural parts are FRP (Fiberglass Reinforced Plastic), and fortunately the FRP hose nipples are threaded and replaceable (in case the my break).
