Engine Fuel injectors/Presure

Fuel injectors/Presure

I see the celica injectors are differant than ours, are they a higher flow rating? The reason ask is that with my intake mods, the cars running a little lean, so I need to look into some differant injectors or maybe raising the fuel pressure. How is our fuel system regulated, anyone know? Thanks

later

as for the celica injector i dunno i believe they are higher flow... the fuel system pressure is regualted but the regulator on the bottom of the fuel pump... thats were toyota puts it since there is no return fuel line on our cars. my suggestion would be to get rid of the one in the tank and buy an adjustable pressure regulator and new fuel rail, then run your own return line. youll still have to get new injector but this way you can control the pressure yourself

Yup, exactly what he said. Make your car have a return line that way you can control the pressure better :wink:
