Installation Notes and Tips

Verify the inlet (lower) position and connector style before installation. Confirm the hose routing matches the original line path and inspect mating surfaces for wear, corrosion, or debris. Because fittings are not included, reuse or source the correct vehicle-specific connection components as needed.
