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.

Art,
I would get a replacement cartridge but if you already have a Ford engine
I wouldn't worry about getting a genuine TR canister. Check the wrecking
yards for about anything that looks like it will fit.
Don't vent to under hood because you run the risk of accumulating gas fumes
which might ignite and cause your day to turn out bad. Boats have a vent
fan
just ot purge gas fumes out of the engine bay for this reason.
You could vent the tank out somewhere where it won't get into the boot but
it would still smell up the garage. I over heard some Model T owners
talking
about first time Model T owners who complained about how the Model T was
smelling up the garage. I guess they were used to modern cars with vapor
recovery systems that prevent just such a thing. Re-instituting the
charcoal
canister will give yo a car that won't smell up the car and keep the
tree-hugging neighbors happy.
