The fuel meter cover does not have to be removed to replace the single fuel injector for the Model 700 throttle body (1987-90 2.5L engine). For the Model 220 and 300, the fuel meter cover does have to be removed to replace the injector.
Remove the air cleaner. Disconnect the negative battery cable from the battery.
At the injector electrical connector, squeeze the 2 tabs together and pull it straight up.
Remove the fuel meter-to-fuel meter body screws and lockwashers.
When removing the fuel meter cover screws, note the location of the two short screws.
Remove the fuel meter cover and discard the gasket.
Use a new gasket and install the injector if removed.
Install the fuel meter cover and torque the screws to 30 inch lbs. (4.0 Nm).
Reconnect the injector electrical connector and negative battery cable.
Start the engine, check for leaks and proper operation.
