Your vintage 900 (with 8 valve engine) has CIS fuel injection... a constant
injection system...the fuel is constantly being sprayed when the engine is
running, from all injectors, all the time. It doesn't matter which line goes
where or what sequence they are in. However, aren't they all a bit different
in length and curvature? If so, that should provide a clue as to where each
line is intended to go.

As to why it won't start after installing the lines, perhaps the injectors
are 'air locked'. The injectors are opened by the fuel pressure. The new
lines are full of air and it takes a while to purge this air out before any
fuel sprays out. You might try leaving the fuel line fittings a bit loose at
the injectors, run the fuel pump manually (if you have a service manual, it
should tell you how to do this) and then gently raise the airflow sensor
'flap' to get fuel flowing to the injectors, which will quickly purge the air
out of the lines. BUT BE CAREFUL, THERE'S OBVIOUSLY A FIRE HAZARD HERE!

Of course the 'no start' problem could be due to some other cause...like the
fuel pump not running, no spark, etc. Believe your car has a cold-start valve
that sprays fuel into the manifold for quicker starts when engine is cold.
If this is working you should at least get the engine to 'fire' when when you
hit the starter, even if the regular injectors are 'air locked'.
