Lesson 2/Learning Event 3
The pump (Figure 20) is used to take samples through the oil filler neck or
through the dipstick hole. The procedure is as follows:
Determine how far the tubing has to be inserted into the reservoir by
using the dipstick as a gauge (Figure 20).
Cut tubing to a length
approximately 10 inches longer than the dipstick.
