Just read the whole lot, and loved seeing your progress. Ive added this to my watch list so will be keeping up with it from now on.
I also have a load of 3d printed parts in my builds! Such a useful toy/tool

Well, to be more specific: in ran, then it cought fire, and then I am rebuilding the engine compartment
It sounds a bit dramatic, and it was, in the moment it happened, but I managed to put it out quickly and the only damage seems to be on the fan shroud and firewall:

I removed the fan shroud and it seems to have started around the #4 injector:

The cable/connector is toast, but the injector is hopefully ok:

After some investigations I found a damaged o-ring on the pressure side of the #4 injector:
o-ring.jpg
So my theory is that there has been a small leak through this o-ring and the fuel/vapour cought fire from a backfire when starting. The cables and paint then cought fire. Luckily I managed to cut the power to the fuel pump immediately, so no more fuel was sprayed at the fire.
So after a day or so with disassembly and cleaning, the engine bay now looks like this:
I have replaced most of the burned wiring, and have a couple of injector connectors coming in today. My son has stripped and prepped the fan shroud for new paint, and I have to ask my wife nicely if she can pull out the sewing machine again.
And I have ordered some automatic fire extinguisher system
But the good news is that it ran REALLY well before it cought fire, so I cant wait to get it back on the road again

Glad you put it out before things got worse. Your car is beautiful.

Me too

I hate to think of how this could have ended.
My eldest son has taken responsibility of the fan shroud and it is getting there.
I also picked up the last few connectors today so most of the parts are ready to go back in within a day or two

I spent a lot of time verifying that there are no gas leaks tonight, before I attempt to start it again, but I struggled with getting the fuel rails to seal properly. Probably because I made my own set of holders and I suspect the do not put an even force on the o-rings.
So I reverted back to the original fuel rails, and now everything is nice and dry:

I hooked up the computer, and I cant get a signal from the MAP sensor, so I need a little more debugging before I am ready for start-up again. I suspect that the wires may have been damaged in the fire, but I will see tomorrow.

It may be somewhere in the thread but I can't find it...
What brand of throttle bodies are they, they have a lovely straight shot from the injectors.
