INSTALLATION
1. Place the high pressure pump (figure 1, item 8) on the mounting plate (figure 1, item 15), and secure it in
place with four bolts (figure 1, item 11), eight flat washers (figure 1, item 13), four new lockwashers (figure 1,
item 14) and four nuts (figure 1, item 12).
2. Install the high pressure fitting (figure 1, item 10) into the high pressure pump (figure 1, item 8).
3. Install the low pressure fitting (figure 1, item 7) into the high pressure pump (figure 1, item 8).
4. Install the low pressure hose (figure 1, item 6), and secure it in place with the clamp (figure 1, item 5).
5. Install the high pressure hose (figure 1, item 9).
6. Install the cable (figure 1, item 4) and connect the wiring using the marks and labels from step 5 of Removal
as a guide.
