Here's what I do: use WD40, or PBBlaster, motor oil, anything that will lubricate the o-rings. It doesn't matter what since you won't be reusing the o-rings (right?) Work the injectors in a conical pattern to try to get the lube worked into/past the o-rings. Then keep working the injectors around while you pull up. Pull up harder. This method has worked for me 9 times out of 10.
Thanks Dave, since I'm only pulling 8 I should be OK.

It just seems wrong to force them. I'm afraid I'm going to break something.

Sorry for the hijack.

Thx for all the info folks.

As to removing the injectors from the intake I guess I was lucky as they either came out or were loosend when removing the fuel rail.

Ken..........more info on those connectors pls.

When we did my SCer install 1 1/2 years ago, DR had the special tool. Man it works awsome! I looked dead simple too.

Maybe PorKen can make a few of those for less than the price of the regular tool which I haven't been able to locate for a long time?

The 928 ones are so aggravating.

Why are they called Audi style connectors when they can be found on many other brand of cars. Did Audi invent them and was the first to use them? For example the Ford Contours and Mercury Mystiques have the same style connectors and have seen others at the wreckers have the push-release style ends too.

AFAIK they are actually Bosch connectors.

you can purchase them new at http://www.diyautotune.com/catalog/f...osch-p-48.html with a pigtail on them, they have them without the pigtail as well.
Only $6.50 a piece hardly not worth replacing them at that cost as these ones dont need that tool.

Maybe. What I meant was 8x9 out of 8x10.

That's just it: if you cannot work them out because the o-rings are bonded with the intake, then when you force them the pintle caps will give up before the o-ring breaks away from from the intake. Then you're sending the injectors off even if you didn't plan to.

I remember that neither you nor Tony had seen the thing before and didn't know what it looked like. Funny thing is: I talked to D.R. a while ago about the tool. He says he always uses his fingers to get the injectors loose because he's broken connectors with the tool. It's the opposite for me. I've broken connectors trying to get them off with fingers, or picks, but have never broken a connector with the tool.

Regardless of whether or not you like the special tool for the injectors, I just don't see how anyone can get the ISV connector on or off without it.

altho why would you pull injectors out that haven't been pulled in a long time and not send them out anyway

Hey I just realised I had a couple of the new style connectors. I got them from 928 Motorsports who describe them as 'fuel injector connector repair kit'. I got them in case I break a couple of connections when I do the intake job/fit new injectors (though I also have the special tool).

The Bosch part number is 1 287 013 003

Presumably you just cut off the old wires at the metal pins, and then crimp them into the new pins so no need for the pigtails?

If the last inch or so of the wires are in good shape then you use a pick (or sewing needle) to depress the barbs for the metal pins and slide them out of the old connector. If the insulation on the wires is poor, then, once the pins are out of the connector, you can slide on some heat shrink to fix the insulation before you install the new boot and connector.

I wouldn't cut the old connectors off unless the wires were totally fried; You never know when you'll need that 1/2" of wire.

I first saw them in Audis, so that's what I call them. They are AMP Junior Timer (like Eagleday sells), but with a spring clip. They are not sealed like the Power Junior Timer, however.

I didn't know the GTS had them, cool. Those are the Bosch numbers. You should be able to order them through any import auto parts place, WorldPAC, IMC, etc. (Carl sells them too.) When I did my '81, back in 2002, I bought them from the Audi dealership, and paid a lot for the connector, and the separate boot!

The shop price here for the female is ~$7 for the kit, which is the connector, terminals, and the boot, which is usually bad too. The male is $13 - pricey, but great for making a pass-through connection.

Most of the time, you can reuse the old terminals by sticking a jewelers screwdriver down the small holes until the tab releases. Then slide on the new boot, bend the tab back gently, and slide it into the new connector until it clicks. (If you get confused, the injectors have a wee (+) sign molded on the side, brown is ground. )

The terminals are used in all the Bosch connectors, even the ECUs, and they are expensive by themselves, so save them. (Or send them to me. )

Nah, send them to ME. (See above post. I'm down with disassembling the connectors; Once you cut a harness there's no going back... )

So, from what I read here, it seem that most of you take off the rail, then pull each injector out one at a time? I found it fairly easy to pull the whole rail and injector assembly out as one piece, then you can work on the bench from there.

Don't know what other people are doing but on MY '85 I....
1.Disconect the fuel rail from the fuel lines.
2.Remove the small metal clip from the injector plug.
3.Remove the plug from the injector.
4.Remove the rail W/ the injectors and put it on the work bench.
5.Remove the retaining clip from the injector/rail.
6.Remove the injector from the rail.
