I soaked my liner with oil over the weekend.
I pulled the hood and soaked it with simple green and water, let stand for an hour.
Rinse.

Prop it up and let it drain.
Let it sit in the sun.
CLEAN!

Oddly enough, that is just what I had found and fixed on my 88. 5 minutes after I had her running perfectly, she burned where she sat. I made the same mistake you did. Raw fuel, heat source and just a little bit presumptious. It could not happen to me. Good job with the save. You will have her running perfectlly now that you know what the issue is. I would replace all of them at the same time, clean her up and continue where you left off getting her perfect. At least you still have her.
Congrats,

Yep, I've discovered a bad fuel damper by pulling the vacuum line at the transmission and subsequently got doused myself with fuel. Fortunately, my car was cold and in the middle of a transmission swap.
Glad you and the shark got through OK. It could have been SO MUCH WORSE.
Was the hood liner that caught fire the OEM unit or aftermarket?

YEP as Colin said you need new plug wires,
as thats where you got the spark to ignite the fire.
Normally you would pull the vacuum line off when the engine isnt running,
so if there was a fuel leak the sparkplug wires wouldnt cause a fire.
I hope that your hand isnt burned too bad.
Goodluck on your project

Super common. The "additives" they are putting in the fuel are apparently "eating" the rubber diaphragms up at a faster rate than the "original fuel" that they were designed to work with did...or they are all just all getting old.
I just looked through my sales history and I installed/used/sold 12 sets of dampers and regulators, last year. (I figure that they are all the same age, so I replace them all, when one or two are leaking, usually.)
I used so many, last year, that I now have "multiples" of them, in stock.

If the diaphragms in the bosch fuel regs are "real" rubber, then the ethanol in the fuel may start to cause a problem over time - *especially* if the rubber is already hard/worn/old from being in there for 20 years. 10% ethanol will not immediately cause issues on natural rubber - but it WILL happen eventually - ESPECIALLY under pressure.
Once it is synthetic rubber, any nitrile, flouro-based material, you are in the clear.

I think this car might be a little to much for you to handle, so now that you have it mostly sorted and titled I think you need to sell it to me for like $5k! 
After all it has now even had an engine fire in its sordid past!

You were absolutely correct!! I just checked other damper & it was leaking a little bit, but the FRP was pouring out
You called it, replace all 3 at once

You don't need a spark from a leaky plug wire. Fuel on a hot exhaust will ignite without a spark. Think 'flash point'.

I've tried it when I was a kid with my buddies, we poured gasoline on the top of a woodstove, it jus sizzled and evaporated. When the liquid finaly found a crack and was exposed to the flames, it cought on fire.
The OP's fire was from an arching plug wire.

So I cleaned up the goo from the hood insulation, repaired the wire to temp sensor 1, replaced the vacuum line, and switched out the crossbar. Once the insulation is replaced, everything will be good as new, hmmm actually better Except for my burnt hand that is!!

The problem is stray sparks.
Which is one of the reasons the first thing I do is change the plug leads on customer cars if they are original.

Colin,
I agree with you... I have seen examples of fuel poured on very hot surfaces just to show that it does not spontaneously ignite. Add a spark however and it is a whole different ball game!!!
