A fuel tank valve apparatus includes a fuel tank (10) having an inlet neck (12) defining a valve chamber (24), a valve housing (30) positioned in the valve chamber, a valve (32) positioned to move within the valve housing (24) to regulate flow of liquid fuel into the fuel tank (10), and a retainer (29). The retainer (29) serves to couple the valve housing to the inlet neck for retaining the valve housing (30) in the inlet neck (12) and maintaining the integrity of the tank (10) and inlet material.
