I have encountered a problem with the fuel system in my '73 Stag (US specs) 
and need some advice.  The original fuel pump is mounted in the trunk as per 
the manual.   The evaporative sysem was screwed up by the DPO when he had the 
car converted over to a Ford V-6 engine.  They removed the evaporative 
canister from the engine bay.  I don't have the canister. The piping from the 
trunk (boot) to the engine bay is intact but is broken right at the top of 
the fuel pump.  You guessed it -- smells of gasoline in the trunk because the 
tank is venting into the trunk.

Questions:
1)  Should I get a replacement cannister, mount it in the engine bay and then 
repair the break (on top of the fuel pump) in the piping from the trunk to 
the cannister?  How important is the system to the engine behavior?

2) Should I repair the break in the piping at the fuel pump and let the tank 
vent through the piping into the engine bay?  Any danger here of an explosion 
when the engine is started?  It appears that's what they did since the break 
does not look intentional.

3) Should I just plug the piping (if so where --  where it exits the fuel 
tank or where it exits the fuel pump?) and leave everthing else alone?  What 
are the ramifications of doing this?  It is the easiest solution.  I know 
that the system was designed to stop the tank from venting to the atmosphere 
in order to lower pollution. The fumes supposedly were stored in the 
cannister and then sucked back into the fuel system when the engine was 
started.  Is there some problem (other than pollution ) with the either the 
tank or the pump if I plug the piping so there is no venting capability?

Any advice would be appreciated.  Cheers.
