I'm going to sink some money into a good , use-it-for-life, sell-it-when-I-die fuel injection system test kit.

I'm not going into business but it's a PITA to have to go out to find/make/buy a fitting when you want to work on the car.

Right now, I have a couple of American gassers and an M116 in a R107 380SL of 84 vintage.

I believe that means I have a K-Jetronic.

Here's the info I need, would appreciate it from people who know the FI system:

1. Is it indeed a K-Jetronic?
2. What's the difference between a K-Jetronic and a KE Jetronic? Should I care?
3. What fittings does the K-Jetronic/whatever I have need so I can diagnose my car's system, as soon as the manual gets here.

I have a manual coming for the Bosch system, but it takes the store 21 days to deliver via Amazon, so they're getting the worst feedback imaginable to mail from Michigan from SC.

4. Any other advice or comments on kits or brands of testers would be welcome. Plus if anyone has extra tools that are home-made, like extra long jumper wires or other suggestions, they are also appreciated.

Thanks

I figured this question belongs here rather than SL, because this is not an SL-model question, but a gasser system question.

Think the best investment would be a fuel pressure tester which will let you verify the control and system pressure.
I went out and bought a tester from JC Witney for about $60 which may not be the best tester out there did let me set the control pressure on my Warm Up Regulator on my 84 380sl - it was running way lean beforehand - now has the needed power and now tackling the Idle Speed Controller -
If you do order the fuel tester make sure it is for the Bosch CIS system and it will come with the necessary fittings or adapters to work with the MB.

Thanks for the info!

Is the" Bosch CIS system" the family name for all the Jetronic systems? Pls clarify

I did look at another set which named BY SIZE every single fitting- metric and SAE-- that came with the kit.

It cost more but I wondered if it still included everything needed for the MB gassers.
