Lesson 3/Learning Event 4
FIGURE 38. TK ITEM 22 - PRESSURE TRANSDUCER.
Used to measure manifold vacuum, air cleaner pressure drops, manifold pressure after
turbochargers, airbox pressures, fuel pressures on SI engines, and other pressures. When measuring
manifold vacuum on SI engines, use snubber, TK item 21, to protect transducer from backfiring
pressures.
FIGURE 39. TK ITEM 23 - - INCH STREET TEE.
Used to tee a pressure transducer into a line where measurements are to be made under flow
conditions. Use with adapters to provide thread compatibility with existing fittings.
FIGURE 40. TK ITEM 24 - - INCH STREET TEE.
Used to tee a pressure transducer into a line where measurements are to be made under flow
conditions. Use with adapters to provide thread compatibility with existing fittings.
