Hi Samba,
I just recently acquired a very solid 1978 Kombi. As the title implies, Fuel Injection and anything post '71 is new to me. It's currently not running but it was a daily driver before being parked in 2010 due to a "miss" (I'll have to pester the previous owner as to the exact symptoms). I just finished clearing out the interior and vacuuming the spiderwebs out of the engine bay and undercarriage. I know better than to try and start a car on seven-year-old gas, let alone sucking it through the sensitive FI system but, luckily, the PO drained the tank before parking it. I just finished the first of many readings of the FI chapter in the Idiot manual and was a bit overwhelmed but I'm sure I get the hang of it.
I'll be on a parts run tomorrow and will be getting some parts for the bus. Other than the usual hoses, filters, points, plugs, coil, etc. required to awaken a sleeping classic, what other parts should I be picking up that might be specific to the FI system?
First priority is to get it running. After that, you can bet I'll be probing the forums for help on getting it smogged. Any other bits of advice or caution on my first Bay Window would be greatly appreciated!

Congrats on the acquisition!

I stole a '78 tin top myself, though mine had sat for 15 years. It was repair shop refreshed to make it trailerable but thats it.

For the FI situation, you can piece it all together yourself, though I saw I think in the English VW magazine a company there that sells a fill FI refresh kit with all the hoses, clamps and bits for about $110. The pieces were cut to measure, just remove and install.

There is also a thread somewhere about the vapor return hoses that all need checking and replacing as well, and in there is a good 2 dozen posts about Marine Valves to help curb fuel flow in case of emergencies.

Another thing you want to check before you run it is if the brake fluid has gone corrosive. Thats one of the main things I am going to have to deal with, though your situation might be luckier.

Also while you are there in the engine bay, check the vacuum line that goes to the brake system.

My 2 cents!

Here's a link to the best fuel,injection manual for your VW...
https://www.thesamba.com/vw/archives/manuals/afc_fi_training_troubleshooting_manual.php

It's a great source for understanding and troubleshooting the FI components. Much more informative than the idiot book.

Best of luck to you! Get it running and get to having fun with it! Dancing

Pull plugs, oil in cylinders, and turn over carefully with a wrench listening for expensive noises. Parked with a miss 8 years ago needs investigation of course

I forgot to mention...
Be sure to buy fuel hose that is made for fuel injection. There's a few threads in here about one that holds up well to the high pressure and to ethanol-laced gas. The brand is Gates, but I don't remember the part number.

Edit: Found it... Gates 30R9.

Alright, the beast (I should say banana) is running. However, it wouldn't run at low RPM and I need it to pass California SMOG so I chickened out and brought it over to the local Bosch expert to play with. So far, he's gotten it running well but he says it has the wrong distributor which is causing the timing to be off and won't allow it to pass SMOG. He's having a hard time sourcing the correct California Emissions distributor, so I here I am looking for one. Any ideas?

You should probably contact this guy if it’s really just a distributor issue.

Is there anywhere I can source a Bosch 0231170093 distributor? It seems like they aren't manufactured anymore.

Looks like this person is selling one:

https://www.bugcity.com/shop/shop.lasso?cid=&s...ort=name_d

That said: you should post the part number for the distributor you have in there - what makes it special compared to any old SVDA? Did these have vacuum retard at idle? Unless there's a technical CA/FI reason you need it (have seen SGKent talk about ECU considerations in other threads), switching to electronic will likely run better:

That's precisely the reason why I need that specific distributor. I'm in the process of getting the bus ready to SMOG (in California) and that distributor is one of two missing links, the other being the crossover pipe for the exhaust system. I did try BugCity but their online ordering didn't seem to be working properly so, I'll try by phone.

The distributor is finally on its way from BugCity but I still need the exhaust crossover pipe if anyone has one (PLEASE!).

Do you have the crossover pipe part number? Have you contacted Ken at the busco?
