I agree, there are no leaks of gas from dripping under the car, seems to be running very rich

I actually experimented with taking sections of F.I. hose and slid them over a 3/16 or so aluminum rod bent into a hook on the end. Then i boiled some water and put the bend rod with hose on it into a soup can filled with the hot water. Let it sit in there overnight and the next day it seems to mostly hold it's shape. Haven't actually tried running it on the car like this yet but doesn't seem to kink the hose too much.

Molded rubber hose is not quite that easy. It’s actually molded in the curing process. Rubber has memory, so even if you get it into a curved shape, heat will cause it to relax back to its original shape. Can you use straight hose? Maybe.

Sounds like you're doing the right thing getting it checked. Often times you will not see dripping, it is more like fuel weeping, vapors escaping through pinholes and cracks where it will evaporate before you ever see drips.

If you park it in garage overnight and smell fuel in the cabin the next morning, that should not be happening. Likewise, if you have an electronic AC sniffer, those are great for finding leaks.

You will find tons of great info here with lots of people willing to share expertise. Welcome to the club!

Hi,
you can use high-quality molded rubber hoses available at Mercedes-workshops.

Look at the upper picture - there is the part# A 201 476 22 26

In an effort to be more educated on all this am I correct in assuming that no 914 owner needs to change to carbs now as all the parts for the FI systems are available to fix any and all of the FI parts ?

No. Most of the FI system is still only available used but for many, the trouble of chasing down parts and keeping them up is still preferable to carbs. Just throwing carbs on an engine still can be less than desirable if you don't change the cam.

I tend to agree. Some examples (subject to corrections from the penny gallery):

- ECU: used only, but these rarely fail
- Injectors: used only, and/or send to RCInjection for testing/cleaning
- Fuel pump: alternatives available
- Aux air regulator: used only, but I removed mine and just blip the throttle for 2-3 minutes on start up until it idles on it own
- Cold Start Valve and switch: I personally never use it (and disabled it) as it only functions below freezing and I don't drive the 914 when iot's that cold...
- IAT: available? Rarely goes bad
- CHT: probably used? But decent examples out there.
- Decel valve: available used
- TPS: new repro boards available
- MPS: rebuild kits available (and they can now be tuned)
- Wiring harness: repros available
- Relay board: repaired/restored versions becoming more and more available
- Distributor/contact points/Djet points: replace it with a 1-2-3 distributor

Now, a lot of this stuff isn't CHEAP, mind you, but it's available. And while the stock EFI doesn't tolerate engine modifications, if you're running a stock engine then the original EFI is the more-driveable way to go.

We got the CHTs, so one less thing. I am trying to make anything that we need to keep these cars running, as the FI is a way better alternative for the cash. As long as it's not stupid expensive.

Great that you are doing that, making more parts available.
