My smog guy failed me today in part for missing a "leaded fuel restrictor". He used to be super lazy about checking for anything, but he said that he got a ticket from CARB, and now he's all strict about everything. Kind of ironic, since leaded fuel is no longer available anywhere, but hey, I guess it keeps me from accidentally filling it up with diesel fuel, haha. Car is a 1980 Euro.

Looking over PET and Google, it seems like it is Porsche part number 928.201.027.03. Attached is a picture of it from 928 International.

Does it just drop in? I was thinking of just machining up some aluminum, but if I can just pay and drop it in, that is the way to go.

Also, how do I find out if my car is the 'Euro S' model with 4.7 liter engine?

Thanks,
Foz

 

Seems a bit redundant. As you pointed out we cannot buy it anyways, so whats the difference.

 

Idiot prevention.

And you can buy it in many places.


Laws like this are not for smart people, theyre for dumb ones. We grow far more dumb people on the roads, than smart ones.

 

It has a couple barbs which dig into the filler neck as you simply push it in.

 

Now that's signature material! Thanks!!

 

 

Yes it just slides down the neck. I have a bad gas tank with one in it. Obviously it was missed in Federalization.

There are several ways to tell an Euro S. The first is the spoilers. Front and rear spoilers came on the S cars both EURO and US. Of course those could be added.

On the engine there is a plate with a engine number M28 / 11 or 12. The automatic had a higher number but the engine is the same. 928gt.com I think has a picture of the plate's location.

The warm up regulator on the front of the engine is mounted differently on the S. It is vertical with the engine on the S. On the non S it is mounted off at an angle.

The intake manifolds are bigger. On the non S models you can pretty much encircle the intake spider with your fingers. On the S unless up have very long fingers you cannot get a full circle. The non S spider is a much rougher casting then the S. The S will be almost smooth with no real ridge. The non S will have a very pronounced ridge on the top and bottom of the tube.

Oh I do think there is a timing hole and maybe a sensor on the back of the 4.7 block - I am not 100% sure on that on the very early blocks.

Then again you can pull a head and measure the displacement on a cylinder.

Of course driving the car should also tell you - but I guess that is subjective.

I cannot think of any other physical differences for the EURO S CIS engines.

 

Podguy - Thanks for the info. Alas, it is not an 'S'. Do you want to sell the one that you have? I'll PM you my phone number.
