Re: [DML] Control Pressure Regulator/Twin Turbos [long]

["Dave Sontos" <dsontos@xxxx>]

The control pressure regulator is a thermostatic pressure regulator. That
means it varies the fuel pressure with changes in engine temperature. There
is a thin metal disk inside the regulator that covers the two fuel ports.
When the diaphragm inside flexes it moves the metal disk open and closed
controlling the fuel flow between the two fuel ports regulating the fuel
pressure on the outlet side. This metal disk is also affected by a change in
intake manifold vacuum, such as when accelerating. An electric heater inside
the CPR helps to open the regulator thereby increasing the control pressure
and leaning out the fuel mixture.

My question really related to what this thing does (well, okay, I know what
it does, but
I've little understanding of HOW). And why this apparently spotlessly
clean unit could cause a massive blockage. I took it apart, cleaned and
blew it out, but can't see how it actually works!
