[6pack] Moss SU Upgrade for TR6

[Navarrette, Vance]

	Alex:

	Lots of people have already chimed in, but that never stopped me from
irritating everyone with my $0.02

	The tubes provide atmospheric pressure reference for the float bowl. The
Zenith carbs have the exact same tube on them, which are routed to the carbon
canister. If the carbon canister is present, you should route them to the
canister in a manner identical to the Zeniths.
	It is dangerous to leave them simply open. Dirt and what not can enter, and
if the float ever sticks there will be fuel pouring out of there as fast as
the fuel pump can pump it. The float stuck on my Mini, and I was lucky I did
not burn the house down by the time I figured out the origin of the gassy
smell. The fuel of course went all over the hot exhaust manifold. Yikes!
	If the carbon canister is gone, you might consider connecting them to the now
unused fuel tank vent line. If they malfunction they will at least push the
fuel back into the fuel tank. With this scheme, you will need to provide a
small vent hole in the fuel tank cap to allow air to be displaced.

Hello all,
A friend of mine just bought a 1970 TR6 that has the Moss SU upgrade. There
are two brass tubes (one ea carb) coming what appears to be out of the fuel
bowls. They are open to the air with nothing attached.

I was told they are over flow tubes and nothing needs to be attached. If you
put your fingers over the opening of each tube, the car will stall out. It
appears that they have a unction. If this is the case, I can only assume that
at the very least there should be some kind of filter mechanism.
