INSTRUMENT PANEL ASSEMBLY (cont)
j. VACUUM-PRESS. Selector Valve. The VACUUM-PRESS selector valve (10) is used to
select either pressure or vacuum.
k. VACUUM REGULATOR . The VACUUM REGULATOR (11) is used to regulate the vacuum.
l.
m. PUMP TEMPERATURE Gauge . The PUMP TEMPERATURE gauge (13) is used with the
thermocouple leads to check the temperature of the fuel injector pump under test.
n. BULB TEMPERATURE Gauge . The BULB TEMPERATURE gauge (14) shows the
temperature generated by the manifold bulb assembly (15).
o. MANIFOLD VACUUM PRESSURE Gauge . The MANIFOLD VACUUM PRESSURE gauge
(16) registers either vacuum or pressure depending upon which way the MANF. PRESS.-CAPSULE
PRESSURE selector valve (17) is turned.
p. PRESSURE REGULATOR.
The PRESSURE REGULATOR (18) is used to regulate the
pressure.
q. MANF. PRESS.-CAPSULE PRESSURE Selector Valve. When testing fuel injector pumps
used on super-charged engines, the MANF. PRESS.-CAPSULE PRESSURE selector valve (17) is
used to select which type of pressure, either manifold or capsule, the MANIFOLD VACUUM
PRESSURE gauge (16) will show.
