How hard is it to change the o rings on the fuel injectors on a 1990 nissan stanza. I have about 2% of automotive know how..Changing O-rings on fuel injectors?
Don't do it. It will be much cheaper to pay a mechanic to do it right the first time. This way you don't have to pay a tow bill on top of the cost to have him replace them. It is generally not too hard but it in very critical to have everything perfect. Hope I have been helpful.Changing O-rings on fuel injectors?
The biggest problem is that the fuel system will probably still be under pressure. Having a mechanic handle things will be your safest bet.
But if you want to change them yourself, here's what is likely to be involved.
1. Drain off the pressure in the fuel rail. There may be a valve for this.
2. Disconnect the fuel inlet and outlet lines from the fuel rail.
3. Remove the electrical connectors from the fuel injectors. This may require lifting out a little wire clip using a needle nose pliers.
4. Unscrew the fuel rail and lift it off.
5. The injectors can now be pulled out.
6. Remove the O-rings and put new ones on.
7. Reassemble in reverse order.
A repair manual such as the ones by Haynes will be a very big help here.
