ABSTRACT:
A vent and pressure relief system for locomotive fuel tanks includes a short standpipe supporting a baffled overflow vessel connected with a drain conduit. The standpipe is made high enough to prevent the overflow of the fuel therefrom during all operating and braking conditions of the locomotive, except for the moment of high deceleration which occurs only at the instant of a full stop. The overflow vessel is made large enough to contain any overflow of fuel from the standpipe occurring during a full stop, and includes baffling to prevent the loss of fuel out the drain conduit and fuel return means to return spilled fuel to the tank. The standpipe, overflow vessel and drain conduit are made large enough to provide an overflow path that prevents tank overpressure when filling, should the automatic equipment of the filling station fail to cut off when the fuel tank is full.
