Removing & Replacing Injectors - EF 4.0L - Ford Forums - Mustang Forum, Ford Trucks, Ford Focus and Ford Cars

Hi guys,

Just wondering if anyone could run me through removing the injectors (and replacing them).

I can pay $220 for cleaning of my current ones, or the same for six brand new from Ford, and learn something in the process.

As far as i can see, it's

Reduce fuel pressure (fuel pump disconnected, start engine till stalls).
Remove air intake piping (think i can do the changeover without removing the upper manifold).
Remove 4 bolts holding fuel rail in.
Use strip of coke bottle to undo fuel line clip from rail. Catch fuel.
Remove injectors + o-rings.

From there, i'm not sure - i don't know exactly how the injectors plug into the rail and engine, and where/how the o-rings and filters go in.

Can anyone give me any pointers, and a quick description of how to go about it? I'm in no means useless, but just want to know i do it properly. And save myself from paying someone else megabucks to do it.

The provider of such info can expect my eternal gratitude. Which is worth something, i suppose.

Thanks!

John.

The o-rings should come off with the injectors,
There are little metal U clips holding the injector into the fuel rail, so remove these before removing the fuel rail.
To remove the connectors, there is a small metal clip that holds them of, basically press this clip in towards the injector, and pull the plug upwards and it should come off.

Dunno about that strip of coke bottle, unless they have a weird fuel connector, but i thought they just have a standard clamp on the fuel line- the EB's do...

Also you may need to remove the return pipe off the fuel reg which is on the back end of the rail.

Thanks - will look at the fuel connector when i have it off, and take it off, whichever way i need to.

Do the injectors just push into the engine - the Gregory's tells me that it does, so that should be easy.

I'm told the injectors have a filter before them - i assume this is part of the injector assembly too?

Anything else to be mindful of?

Make sure you take your fuel cap off. This will help pressure wise.

Yes its quite easy. I find some light oil or carefull amount of grease on O rings helps them slide in...

Fuel cap off ???? Never done it !!!

so cleaning them is same price as new ones or is that trade price or somethin

is there anyone that does exchange? it might cost a little less...

I just picked up today 6 brand new injectors for my I6, total cost $145, at trade prices of course

They told me that Ford dropped the prices on injectors for a short time and my local dealer picked up quite a few, Ford has since upped the price but my dealer still has 60 odd in stock. excellent deal!

Repco do change over reconditioned injectors for $145 trade. They quote you $260, but tell them you want trade as $260 is dearer than brand new ford ones.

The biggest bargin at the moment is at Rex Gorrell Ford in Geelong. Injectors are $16.50 each, so your looking at $99 for a full set of brand new ones.

Thats if you want to do it yourself.

Hrm... Can also get a fuel system flush and injector clean from Ultratune @ $130. Now, i was sceptical, but it uses a system called 'Carbon Clean'. A quick google seems to give a lot of positive feedback, and removes the chance of me rooting the car whilst trying to change injectors, or getting 1/2 way through and reaching a dead end, and saves me a drive to Geelong.

WTF is up with Bayford quoting me $79.50ea? I mentioned that i had quotes of half of that, and a quarter of that, and he said 'that's the list price' - no offer to match, or even go close. Weird.
