Question: How do you make sure you don't fill the tank full enough to get overflow into the fuel vapor hose?

Most shops say 10 years is about the lifespan for an OEM charcoal
cannister. The Pantera is 40+ yrs old and the Mangusta, nearly 50. I
suppose one could solvent-wash an old one to maybe get rid of oil &
gas-varnish, then heat the cleaned can in an oven you never want to use
for food, to 'activate' the charcoal again. Much less messy is finding
a much later model cannister from a low mileage junker at Pick 'n Pull
that's the right size to fit your bracket. Personally, I run the
breather hose straight into the bottom of my air cleaner, eliminating
the charcoal cannister and 10 ft of rubber hose.

Dear Mike, Asa, Jordan and Jack,
See $$$ below.

While the engine is out, I have been tidying up the engine bay. For
some
reason, I noticed that the hose that connects the gas tank vent to the
factory charcoal canister is braided stainless steel. It seems to
be the
*only* stock factory braided steel hose in the entire engine bay.
>>>The original stock fuel line was also braided, although it wasn't
shiny so it's not obvious. There was a flex hose from the fuel tank
pickup to the inlet of the fuel pump, then a metal hard line from the
output of the pump up the front of the motor and across to the
passenger side, and a short length of hose connecting it to the
carburetor.
$$$$$ Hmmm, it may not be stainless steel. It is braided and it has
punctured my flesh. It is not covered with braided fabric. Perhaps it
has been changed. I assumed that it was stock. Perhaps the stock
vapor hose was braided fabric and it resembles the grayish tarnished
steel braided line that I have found in the engine bay.

why that
seemingly lowly hose was worthy of the stainless steel braided hose
treatment???....to vent simple gas tank vapor??

Charcoal
Canister from its stock location. I suppose that the charcoal is
kaput.

lifespan is purported to be?

the proper
tool. I assume that if one could open it then it might be possible
to dump
in another dose of activated charcoal for another four decades.
>>>It all depends on how concerned you are about the environment. I
would suggest that the amount of damage you are doing with your
camshaft choice and right foot is orders of magnitude greater, and if
you really were concerned, you would address those issues first. :>)
$$$$$$ My interest was is in normal engine function over
environmental concerns. Thank you for complimenting my camshaft
choices and driving style..
> Second dumb techno questions regarding the Pantera
charcoal
canister: for those that worship at the stock original altar, does
anyone
maintain their charcoal canisters?.....or are they inoperative stock
adornments of the stock original engine bay?
>>>Nobody maintains them. Whether they still function of not is a
matter of conjecture. I moved my water bottles so one now lives where
the canister used to be, so my beautifully painted and detailed
canister and associated bracket is in a box.
>For those that have modified their Pantera and worship at the
laissez-faire
altar, do you completely remove it? ..add a modern replacement??
>>>As it has no performance impact, and simply represents a token nod
to environmental concern, you can either leave it in place or remove
it; it won't have any measurable effect on performance. You will need
to decide where and how to run your fuel tank vent hose if you chose to
remove the terminus formed by the canister however. There is
certainly no harm and perhaps some minor benefit by leaving it in
place, but it only really works if the second hose is connected from
the canister to the underside of the air cleaner, so that fumes are
extracted through the canister and into the air cleaner, to be burned
by the combustion processa|..
$$$$$ That is correct. With my laissez-faire engines it would be
hard to plumb it back to the air filter and it would also detract from
a functional tidyness in the engine bay. I do think that my highly
valuable stock original charcoal canister and braided hose will soon
reside in the parts warehouse, labeled from future retrieval in the
distant future.
Back to our normal drivetrain re-assembly and installation
programming........
