Interesting thought there. Could there be anything to it? If this were true then wouldn't we be seeing lots of immolated European K-Jet cars - which were made by the millions during a 21 year stretch - all running the same fuel pressures that a D runs?
See excerpt here from Wikipedia showing all the car mfgrs that used similar/same FI system as a D:
K-Jetronic (1973–1994)
...The 'K' stands for German: "Kontinuierlich", meaning continuous. This is different from pulsed injection systems, in that the fuel flows continuously from all injectors, while the fuel pump pressurises the fuel up to approximately 5 bar (72.5 psi)....... K-Jetronic debuted in the 1973.5 Porsche 911T.....and was later installed into a number of Porsche, Volkswagen, Audi, BMW, Mercedes-Benz, Rolls-Royce, Bentley, Lotus, Ferrari, Peugeot, Renault, Volvo, Saab, DeLorean and Ford automobiles.
So, is a DeLorean susceptible to fire? Probably. Is it more susceptible to fire than millions of European cars made over a 2-decade long period? Probably not.
I am setting aside whether the fire in this particular unfortunate incident was or was not fuel-related. I'm only commenting that whatever else is good or bad about cars made with K-Jetronic systems there were lots and lots of them made for a long time and they all pretty much behave like each other with respect to maintenance, trouble-shooting, reliability and parts.
