| ADJUSTABLE PRESSURE SWITCH
This switch determines the point where the system starts to
inject. It is normally fitted to the vacuum side of the inlet
manifold (2D mode) for applications where load signal (throttle
angle sensor) or manifold absolute pressure sensor (MAP sensor)
is available. The switch is a 'normally-closed' type, adjustable
range is between 3-30psi, factory set at 10psi.
HOOD This Nitride
rubber cap is for protecting the electrical contacts on the
pressure switch from the harsh environment in the engine bay.
STAINLESS IN-LINE WATER FILTER
Apart from perfoming the normal function, this filter can
be back-flushed and re-used again and again. In hard water
areas, occasionally clean the filter in a small glass of diluted
WATER JET The jet is made of
nickel-plated brass with two spiral grooves cut into the centre
insert. Water travels through these grooves, acquiring a swirling
motion before leaving the small hole on the tip: the main
function of this arrangment is to cause an atomising effect
and turn the water into a fine mist. Of course a pressure
of at least 3 bar is required. Jet sizes from 0.5mm to 1.0mm
are available in 0.1mm increments. 0.5mm size is supplied
with the standard kit, but alternative sizes can be supplied
on request. Thread size of the jet is M8x0.75mm: this is not
supplied with the kit but can be made available on a loan-and-return
basis if necessary.
FUSED LOOM (pump)
The 3-wire loom is equipped with a 10A inline fuse. Wire size
is very important as the pump draws large currents at start-up
of every stroke (45 times/sec.): make sure a 30A wire is used
if extension is necessary.
fasteners are made with high quality 316(A4) grade stainless
steel: lower grade stainless steel does suffer from corrosion
and pitting under the harsh environments of the engine bay.
HOSE The hose
is made of nylon, whose natural strength can sustain pressure
of over 12bar at 80°C. Lowest operating temperature is -40°C
@26bars. The colour supplied with the kit is semi-translucent
white, but red, yellow, green, blue and black are available
