ABSTRACT:
A fuel tank construction comprising a tank and a sump is disclosed which construction includes a float operated water separator. The separator operates automatically to drain water which has separated out and accumulated at the bottom of the sump. The separator is in the sump which is secured to the underside of the tank. The tank has an opening through which the sump and tank communicate, and there is a normally open one-way valve in this opening. This valve prevents water and solids flowing back into the tank from the sump if the tank construction is inverted. Within the tank there is a filter through which fuel flows to reach the fuel outlet line. The filter is normally spaced along the tank from said opening but can be displaced to a position overlying the opening when access to it through said opening is required for servicing purposes.
