✔ Use correct mounting bolts (7/16"-14 UNC-2A), spaced 4.75" center-to-center
✔ Ensure ports are oriented downward (90°) to prevent moisture buildup
✔ Use thread sealant on 3/8"-18 NPTF ports to ensure leak-free operation
✔ Orange Alert provides visual stroke feedback—check stroke post-installation
✔ Torque mounting bolts to 35–40 ft-lbs
✔ Torque air line fittings to 18–20 ft-lbs
✔ Replace diaphragm during install—do not reuse old rubber components
✔ Test system at 100 psi; pressure drop must be ≤10 kPa over 5 minutes
✔ Complies with FMVSS 121—verify free stroke of 1/4"–3/8"
