12. This is the pump assembly installed, but not yet wired. Notice the rubber hose used to protect the high-pressure hose from abrasion where it passes through the frame. The rest of the hose was secured with wire ties. Wiring the (up and down) solenoids is straightforward, using the included 20-foot four-gauge welding cable and the secondary wiring for the dash-mounted switch. As with the pressure hose, be sure to keep the wiring secure to keep it from rubbing through the insulation over time.
