Thanks Hans. I should have made it clear that both of my SL's were/are equipped with 4 speed manual transmissions. Sorry for the confusion folks.

So does this mean that there were some US cars delivered with the micro switch on the firewall, but none of the other pieces to shut the pump off?

Does the micro switch serve any other purpose?

John,  does your car have the two solenoids on the pump?

Cheers,

Not sure when emission controls were mandated but this is the way the car came. There is a micro switch on the the throttle linkage to shut off the FIP when letting off the accelerator. Not sure if that qualifies.

Hi, John,

May we have a picture of this microswitch when you have some time?

Hello Naj,
 Here is a photo of the Micro Switch. A little "grimey" after 47 years but still works :)

Thanks, John,

I believe this is a throttle position sensor.
There are switches on the shifter lever mechanism which when in 3rd or 4th gear allow the fuel to be cut off when coasting.

Not a hybrid after all!

I will look at Kemal's 70/71 car at the next opportunity.

Did we fuel jack this thread?

John (49er), In the photo of your 250sl engine compartment that Artur posted, On the top rear left (drivers) side is an engineering tag (rectangular). Do you happen to remember what it said? I had an almost completely destroyed label in that exact location. All that was left was some off-white or yellow remnants, red font, and the outline. The size matches the "Achtung" spark plug warning sticker that I have seen before but cant be sure.

Here are two pictures of my 1966 230SL engine compartment.  I have it owned since new.  Only significant differences for when delivered are:  1.  Valve cover polished  2.  Radiator expansion tank chromed  3.  New firewall cover

Sorry Tyler, my memory is not THAT good :) I enlarged my photo and can make out an "Achtung" in the upper center and what appears to be red lettering. Sure wish I took more photos back then.

Hello Paul, I just happened to see your post here (and now read your others as well) and do hope to hear more about you and your car as Jonny and Achim have suggested. As you can see from my post signature, I too am an original owner although not as long as you. Next May will mark 50 years of having a Pagoda in my garage. We sure were smart to get one of these back then weren't we? ;D

Thanks John! Thats all i needed, Verification. Was kind of a strange place to put that label as the label crosses over the little indent cutout on the valve cover. Yours looked the same way, a little tear in the label. The 250's are the odd duck when it comes to certain things.

Having just seen this topic I thought I would post a couple of pictures of my recently restored engine bay. All the work was carried out by Roger Edwards Motors of Amersham England. Instructions were to get the engine bay back to as near to original as possible, I think they achieved 90% of what I expected.
