We've used the Facet fuel pumps on our off road, on road, even race cars for years.  Never had one fail and they've been through it all.

Subject: Fuel Transfer Pump recomendations

I'm in the process of installing my South African 15 gallon auxiliary fuel tank in my 90 Westy and I'm not happy with the 12 volt Fuel Transfer Pump that came with the kit. I think the first time I drive in the rain it's going to get water-logged. Does anyone have a recommendation for a weather-proof transfer pump? And maybe a weather-proof relay?Thanks,Mike M
