How To Install Injectors

Recommended Posts


This is for the FG.

Before starting the job, ensure the engine is cool and the area to be worked on is free of debris and contaminants.

I can't give an indication of tool sizes as I haven't done the job, but will give a guide as per the workshop manual.

1. Relieve fuel system residual pressure. This can be done by removing the fuel pump relay and running the car for a while.

2. Remove intake air ducting.

3. Disconnect the wiring harness from the tops of each injector. Be careful as these may be brittle depending on age.

4. Disconnect fuel supply and return lines from the rail ensuring they are marked for correct orientation.

5. Disconnect vacuum hoses from the fuel pressure regulator.

6. Disconnect the wiring loom from the fuel rail.

7. Remove the retaining screws from the brackets that attach the fuel rail to the inlet manifold.

8. Remove the injector to fuel rail retaining clips on each injector and remove.

You should be able to remove the rail completely and each injector now. Installation is the reverse of removal. When fitting new injectors a light smear of engine oil on the o-ring will do as lubrication. DON'T use any form of Vaseline or petroleum jelly as this can cause all sorts of greif.

The torque for the rail to manifold brackets is 19Nm.

This method is impossible ive tried and you do have to remove the intake manifold,as you cannot get access to the rear bolt wish it was as easy as you say it is,ive done all you suggestions,but unfortunately my mechanic has to remove the manifold.

Your mechanic is a peanut 

 

injectors on a FG falcon takes 30 minutes and a B series 45 minutes 

 

no intake manifolds need to be removed on either

I did this recently and the instructions above are absolutely correct.

 

The only detail I would add is when disconnecting lines from the fuel rail, just disconnect the connections to the hardlines under the car but leave the rail connections intact. Then lift the rail out with the fuel lines still attached.

 

Haha my mechanic just quoted $1500 to do the timing cover seal and wants to pull the engine. Even Ford only quoted $1000 and said they leave the engine in.

You don’t need to remove any lines from the rail for Christ sake, what are you lot doing 🤨

 

if you can pull the line back 20mm ( which you can ) you can fit injectors in situ and bolt the rail back down 

 

Stop over complicating things

I started that way, but found the 20 seconds it took to disconnect the lines under the car and lift the rail out made the job much easier. I could then quickly fit the new injectors and reg on the bench and then drop the assembly back in.

Jet would have fitted 100s of sets . He would have the procedure down perfect. 

 

My mechanic said he also may have to remove the fuel tank.

My mechanic now advises me the chrome is peeling off my grease nipples and tyre pressures are low.  He has suggested once these items are rectified the injectors should drop straight in..

 

I give up. Now my double overhead reverse twin cam door handles  are showing excessive wear.

 

HELP. What should I do........
