 FLOAT VALVE - REMOVAL/INSTALLATION
__________________________________
 1.  General_______
 A.  There are four float valves of the fuel vent. The float valves are found on the inboard side of each end rib in the fuel tanks. The float valve lets air move out of the fuel tank during refueling while it keeps fuel out of the fuel vent system.
 B.  There are two types of float valves: a float-actuated vent valve and a fuel vent float valve.
 C.  This procedure contains four tasks. The first task removes the float-actuated vent valve. The second task installs the float-actuated vent valve. The third task removes the fuel vent float valve. The fourth task installs the fuel vent float valve.
 TASK 28-13-01-004-001
 2.  Remove the Float-Actuated Vent Valve (View A, Fig. 401)____________________________________
