LM964

Page 108 of the Katalog. Carbon Cannister #964 201 017 00 (pre '92) / 221 01 (post '92). Clamp # 999 512 506 02 (a 106 x 25 jubilee clip tbh).

Hope that helps.

If the clamp is rusted solid, just cut away and replace with a large stainless Mikalor clip.

Thats really helpful Top man thank you!

Is it still available? Some sites say that it is not.

Also found the carbon cannister as 993.201.221.01.

Ordered from my local OPC in UK. 2x items at Porsche GB, so no problem. It is now superseded to a 993 item.

The parts guy did say the cost, but my hearing went bad as it always does when they speak about part prices. lol! I'm sure parts guy said over £200 or similar. More OPC wallet hoovering Ouch!!!

I've spent so much money this year on parts i didn't need to replace chasing down problems. The only consolation I keep saying to myself that the car will be soo good when get to the end of it. Pah, who am i trying to kid

i have the same issue on my c4 and have just learned to live with it.
My indy suggested it was a crank sensor but I have always leaned towards fuel pressure dropping off when everything is hot.
Great that the issue can be rectified by replacing the charcoal canister.

If you have a hard time finding a charcoal canister, it can be rebuilt.

The internals are foam, some big metal "washers" with holes, a plastic pipe and active charcoal.

You can cut it open at either end about 2/3 of the way (not exactly in the middle) and replace foam and charcoal. Then close it up again and seal it with epoxy.

Put back and voila, all is good.

Not the greatest looking repair, but if in need it can help.

I hope replacing the cannister solves your issue backitoff. It worked for me but it would be daft of me to assume it cures all start up maladies. Let me know how it goes. Took me a while to track down info on this but it paid off in my case.

I replaced my Carbon canister recently, sourced it from Rose Passion in france, quite a big saving to be had...

I feel your pain as my 964 is a lazy starter and when warm it used to run off sometimes...
Replaced the check vavle (Which is on the end of the fuel pump for those discussing earlier).
Replaced the carbon canister which hides behind the wheel well liner so out of sight.
Car runs a little better but still doesn't start on the button... The hunt continues!

Thanks for your input. Rose passion seems a lot cheaper than OPC :-0

I think I'll change the cannister, replace the ignition switch, and most likely the fuel pump and check valve.

I have already replaced the DME, Crank sensor, Battery, ECU, Fuel pressure regulator. Cleaned the earths, Checked idle microswitch, and had an auto electrician remove all traces of aftermarket alarms and immobilisers.

Surely, I cant have missed anything???

How about the fuel regulator? On the cis cars the fuel accumulator goes bad and doesn't maintain pressure in the gas lines and heat vaporizes the gas and hard hot start. Number 17 in the pic.

Hi Wilson.
I have already replaced the FPR. Its on the list in my last post. Appreciate your input Thanks.

Backitoff, any update on replacing the carbon canister. did it solve your hot start issues????

backitoff

I was going to order one from my local OPC but when I called and got the price, it was ridiculously expensive!
Glad I didn't go for it (as I normally do) because it turned out to be the crank sensor plug connection was bad!

I do intend to take the carbon filter apart and replace the filter at some point. Probably when I do the bodywork.
Thanks for following up!

Good to know Backitoff.
Mine is in on Friday as it is really starting to get on my goat now.
Will get my indy to run through all the above mentioned parts that could cause the fault.
