Andrew, if you want to 'keep it Triumph' have a look at 
www.rimmerbros.co.uk/tr6/images/112a.gif and 
specifically look at ref nos 42 and 43 on the panel of images + items 42-47 
inclusive. This is the 
inertia fuel cut-out switch fitted to all injected TR's and the 2.5 litre 
injected sedans. Speaking 
from personal experience over the years they are *very* reliable - like they 
immediately shut-off in 
an accident, violent skid or the car going inverted. They are wired through the 
ignition. They also 
have a button (illustrated) to re-set after cut-off and which also allows you 
to turn off the fuel 
pump if you need the ignition switched on but don't want to start the engine or 
flood the carbs.
Usual faffle about NFI or promoting Rimmers. Doubt you'll get this particular 
switch through any of 
the US suppliers and also worth noting it should be a lot cheaper in $'s 
following the collapse of 
the #/$ exchange rate.
