In a fit of boredom (OK in reality I'm busy as heck at work and there's
no time for any big fixes on the TR6) I bought all the bits required to
build my own leak down tester.
The parts list came from these sites recently posted
http://www.briggs-racing.com/tech/leakd.htm or
http://members.tripod.com/~Wrenchbender/leakdown.html
My question is related to the differences in the two testers on these
two pages. One shows a regulator and pressure gauge separted by a
tightly reduced (1mm hole in expoxy filled pipe) segment and in line
with the air flow. It is noted the restricted piece is vital.
The other has a the air gauge mounted to the regulator directly, but
there is no mention of a restricted piece between the two except in the
parts list there is a 'close nipple' noted.
What is a close nipple? Is it a restricted piece of pipe between the
gauge and regulator? I of course have the bits to build this second
type but am not sure if I need this restricted bit of pipe......
