Any spillage is automatically collected and routed to a valve that drains into a pail for proper disposal. There is no free flow of fuel into the bilge. Also we installed a catch under the stuffing box with an automatic pump. The packing leaks very little, but just enough, so this system keeps the salt water out of the bilge when steaming, also (bilges are color white).
