ACDelco Professional 36-365451 (19147648) Power Steering Pressure Line Hose Assembly - Replacement for GM Vehicles - Durable & Leak-Proof Design - Perfect for Chevy, GMC, Cadillac, Buick Models - Ideal for Highway Driving & Heavy-Duty Use

This hose fixed a problem I was having in getting the high pressure line to seal on a rack and pinion replacement job for a 2003 Trailblazer. The factory caused a design change in the high pressure part that eliminated the (very expensive) little rubber hat seal in favor of a more traditional captured o-ring design. The o-ring design is MUCH better, but buyers need to realize that THE OLD SEAL MUST BE REMOVED -- something that the instructions say, all the on-line manuals say, and all the forums say -- but which many people ignore and then later struggle with. Further I also found that installation was made easier by tying the two lines together in the steel clamp with a nylon wire tie. That locked the two lines (high pressure and low pressure) into one unit that could be easily inserted into the rack and pinion without struggling to get all three parts (two lines and the steel clamp part) into place at one time.Fit and finish were good and the line fits and works well! It hooked to the power steering pump well and I found that it sealed first time, unlike the old line with that ever-so-cumbersome hat seal. For those in need, part number of the factory (only) stock SEAL is: 26080380 and cost is approx $20 each.
