Some time ago I removed the Cold Air Box on my car's H6 carbs which were part of the Le Mans kit installed by the original owner in 1956 and replaced it with velocity stacks. I have not yet removed the short "Vent and Drain Pipe" which went from the top of each float chamber through a hole and grommet and into the CAB. If the drain pipes serve any purpose it stands to reason that I should now replace the short ones designed to work with a CAB with non-M drain pipes which lead down and, I assume clear of the exhaust manifold and pipes.
Moss pictures what I believe is the correct non-M part on p. 24--pn# 97/451-250 but describes it as "Vent and drain pipe to cold air box, 100 M". I believe the illustration is correct for the H4 original setup, not the one for an H6 Le Mans CAB setup. I think this may be important as I seem to recall that the the two vents utiize different fiber washers, the non-M setup using a conventional washer and the M setup using a "scalloped" or vented washer.
Can anyone please enlighten me on the correct parts I should be using?
