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.
