put the injectors into the rail by twisting them gently and they should seat right in. on cleaning them, take them to an injector company. i took mine to linders fuel injectors here in indianapolis and they charged me $25 each injector. they completely rebuild them and they will tell you if they are good or bad by ohm readings.

one of the most important things: Before you put the manifold back on, jumper the yellow two pin connector on the passenger side strut tower. Key should be in the "ON" position." That will pressurize the fuel system, and if there is any leaks you will see it then without having to run the engine.

When installing the injectors, put some oil on the lower O-ring. This will make the installation easier and prevent the O-ring from twisting or tearing.

the o-rings hold the injector in the rail. the nozzle slides into the housing and the inlet with the screen pushes into the fuel rail. the top is easy to distinguish due to the connector being at the top.
