Default Thanks for the help, would be great if someone could point me to K-jetronic info

Yep I have never seen this system fully assembled and any info with fuel routing fom the fuel distributor, WURM and vacuum routing would help me speed up my process.

I then have to install the, hoses, starter, exhaust and fuel tank, I have tomorrow off and hope to be firing it up, (fingers crossed)

Wish me luck, thanks in advance

What model year and US or Euro, S?

Routing from the fuel distributor is to each injector.

What is the status of your car, running, used to run, pile of parts?

Sometimes the group at pelican can be a bit more active with CI$

"firing" it off isn't a good way to talk about a 928.

CI$ has to be microscopically clean to work well, and each of the parts has to be working correctly or it may not run, so its good to have everything freshly cleaned, rebuilt etc so you don't keep flushing junk into the next part in the chain.

here you go. It is not specific to the 928, but the system is essentially the same. There are a number of very good you-tube tutorials on the k-jet as well.

Thanks for the help, good point, this is a pile of parts, but thankfully the PO bagged and labeled everything quite nicely.

Thanks for the info, at this point i will plan on having to take it all back apart.

after reading more I assume I will be taking it back apart to change seals on the fuel distributor and etc.

from what I have been told, I think this car ran 4 years ago and broke its timing belt, the PO started to part it out but had second thoughts. I purchased the car w/o engine and a few other pieces.



Quick Reply: Thanks for the help, would be great if someone could point me to K-jetronic info
