I do not think there is too much that you have to do.  You will need a high
pressure cylinder to contain the pressurized hydrogen (I think it is stored
at about 3000 psi) and you will need a few pressure regulators.  Actually,
you should talk directly with someone who has done it.  I have an acquain-
tance named Mr. Ben Jordan who converted a model T automobile to run on two
fuels, one of which is hydrogen (the other is gasoline).  I have seen the
car and as I said, the conversion does not look that complicated.  The spark
timing will also need an adjustment since the flame speed for the combustion
of hydrogen is much faster than that for gasoline.
Check in the library under alternative fuels.
