that upper tube does not move out of alignment).
6. Drill 7/32 inch holes in lower tube using upper tube
holes as reference (see Figure 26).
7. Remove the tubes from unit and assemble the upper
(item 2) and the lower tubes (item 3) using three
#10-24 x 3/4 inch hex washer head screws (item 4),
three #10 washers (item 6), and three #10-24 nyloc
nuts (item 5). The screw head should be installed
to the inside of the tube to provide minimum
obstruction to flow. Make sure that the upper and
the lower ends are oriented properly as the tubes are
assembled. (Parting lines should roughly be lined up.)
