I was having a look under my fuel rail covers tonight. Wanted to get familiar with that area as have fuel pressure gauge on the way, also am thinking of doing intake R&R and replacing some injectors.

Looking at the write-up for intake removal there's a reference to a special Bosch tool for disconnecting the 2-pole connectors with the wire clips. I had to fiddle with this when I was testing the Temp II Sensor and it is fiddly (though I understand newer versions of the connector are just press to remove!).

Have been googling like mad and can't find this tool anywhere. Please does anyone know where I can get hold of one? It looks like it would be a real time saver and good for reaching other connectors beyond finger reach!

TIA,

Adrian

You're looking for a 9266 tool, porsche P/N 000.721.926.60. 928SP sells them, current price is $83, which is outrageous highway robbery for what it is, but OTOH it works perfectly and I can't imagine how one would disconnect or re-connect the ISV connector without it. Maybe if you're missing a thumb and a pinky on one hand....

I use a regular flat head optical screwdriver and a little wiggling.

Thanks Rob - I've found it on the 928 Specialists site. Will probably be tempted by some other stuff while I'm there...

Maybe I have an unappreciated talent, but I have never failed to get one of these off by wiggling it side-to-side a few times while tugging gently. First one side will pop slightly, then the other and it's off.

The main thing to watch out for when removing the FI connectors, Porsche tool or not, is that the wire clips can easily fly off into space. They are held on solely by a dab of melted plastic on the closed side. This plastic dab fractures over time, leaving the wire totally unsecured. You'll see what I mean, hopefully before you lose a clip.

Adrian-

Bill is right about the FI connectors, the tool really isn't necessary for those. I bought the tool 'cause A) I'm a tool junkie, and B)- didn't think I could get to the ISV connection. I'm sure plenty of folks have gotten to it by removing the intake, rotating it 180o upside down, taking off the throttle body (4 13 mm bolts), and then disconnecting it. Maybe it can be reached without removing the throttle body, dunno.

The injector connectors can be tough to remove by hand if they've not ever been disconnected. Mine were really tight, and even with the tool, some were tough. The second time I took the injectors out, the connectors came off just by wiggling as Bill describes.

Hi Rob,

Looking at mine I don't think they have ever been disconnected these 20 years!

Say a clip did fly off (and in my sad experience small parts disappear into warps in the space-time continuum, or failing that somewhere equally inaccessible in the car) does it make much difference to the integrity of the connection? I remember when I took similar connector off the Temp II sensor it seemed pretty secure whether the clip was on or not (as it happened I didn't lose it that time!).

I know that the reference to the Bosch tool is in my intake write-up. But, when I wrote that a zillion years ago the tool was $35? Or about that. $83 is a ridiculous price. However, unless you have strong fingers and rather long skinny arms the tool is a real time saver.

Where's Porken? I'm sure he could get a batch of these made and make a nice profit selling them for <$50. I'd take two.

I'll go out on a political limb here and suggest that the "price" hasn't changed all that much. The US$35 old "price" was about Euro$45. Now that same Euro$45 is about US$65. Let's see, eighty three minus sixty five is eighteen. Divide eighteen by a zillion, and the annual inflation rate for connector tools doesn't look at all bad.

By the way, if the clip flies off into nowhere you can make replacements out of music wire available at any RC hobby shop. I've had to make two or three replacements, myself. It is frustrating when you are nearly done with a project and one of those buggers is gone.

Connector tool arbitrage. Tell me there isn't a bin of them sitting in a warehouse in the US since the '80s. Bosch USA's just paying the inventory cost and I'll bet its fully depreciated now anyway.

Regardless of the price of connector tools in China, I still think Porken should make up a batch out of less stringy metal than the original and sell 'em for half the inflation-adjusted-converted-from-current-weak-dollar-to-strong-Euro price.

Ditto.

I'm currently replacing every clip with an Audi style with an actual release mechanism built in.

You need the clip unless you want to tie-wrap it on somehow. I bought some replacement AMP connectors on eBay for $2 each just to get the clip that came with them.

In this case the clip has a small "hand" on the end of each arm that prevents them from coming off and requires no plastic dab to retain them. So simple and so effective. Here's an illustration:

These are the bomb!! Push the wire, they pull right off:

Bill's method works, but be careful. Some of the base connectors can be brittle and break - especially on the hall sensor.

I do not take any chances after breaking a few of the based. I use a small probe and pull the wire clip back and sometimes completely off. The the connector slides off with out any stress on the thing it is connected too.

Dan the Pod Guy with no more broken connectors.
