Propane Fuel System Leak Test
PROPANE IS EXTREMELY FLAMMABLE. NEVER USE AN OPEN FLAME
OF ANY TYPE TO CHECK FOR PROPANE FUEL SYSTEM LEAKS.
Always inspect propane fuel system for leaks after per-
forming service. Check for leaks at fittings of serviced or
replaced components. Use a commercially available liq-
uid leak detector or electronic leak detector. If using both
methods, use the electronic leak detector first to avoid
contamination by the liquid leak detector.
