Todd the age old accepted method is to use a pressure/vacuum gauge. Just
your run of the mill vacuum gauge (test gauge) from a place like sears.
I've had mine for years and it comes in handy on ocasion.
You check for (1) pressure
place the gauge between the pump and the carbs, just T into the rubber
lines. The pressure is usually 3-5 psi check the manual for sure. This
is recorded when cranking.
You check for (2) Vacuum
Insert a T into the line between the tank and pump. Crank the engine
and you should read a certain amout of " Hg (vacuum) the amount escapes
me at the moment. Also do this while cranking.
You check for volume
open the rubber part of the line from the pump and extend it to a
coffee can and check for volume. this is done while cranking and their
is a usual spec. gal/qts per sec. or min. Check the manual.
It really isn't too tuff to do and takes all the guesswork out of it.
Same rules apply today but we operate fuel systems at much higher
pressures for fuel injection systems.
Good Luck

71 and 74 TR6's
(both my 74's parts car and real car had overiders and no triumph badge
on the bumper. The big change came in 75, 76 I presume)
