What to do if my GMC Air Compressor has insufficient pressure?
- ZZoe CoxJul 29, 2025
If your GMC Air Compressor has insufficient pressure or decreased outlet capacity, several factors could be the cause. Ensure the drain cock is closed; if open, switch off the unit immediately and close it. Inspect all air fittings for tightness and leaks, reconnecting quick-release fittings if necessary or replacing defective ones. For male or female fittings leaking around the thread, tighten with a spanner or reapply Teflon tape after examining the fitting's condition. Also, examine the air hose for any holes or tears and replace it if defective. A dirty air filter cartridge can also cause this issue, so clean or replace it.
