Fuel Meter Cover Assembly
The fuel meter cover assembly contains the fuel pressure regulator assembly. The regulator has been adjusted at the factory and should only be serviced
as a complete preset assembly.
CAUTION: DO NOT remove the four screws securing the pressure regulator to the fuel meter cover. The fuel pressure regulator includes a
large spring under heavy compression which, if accidentally released, could cause personal injury. Disassembly might also result in a fuel leak
between the diaphragm and the regulator container.
