[TR] TR3a vacuum line

[Carl TR]

Does anyone know of a source for replacement vacuum line

Late TR3A
screw type connections

at the distributor:  8mm w/1mm thread nut
at carburettors: 7mm w/1mm female end

I have the 7mm fitting that was in the carb housing but might as well 
replace both if I can find them.

What diameter is the tubing.  it appears to be about 1/8 od but since the 
fittings are metric - it might be a metric size tube.

Also - what length.   I figured at max a length equivalent to the fuel line 
from near the distributor to the connection at the carb.

Thanks
