Quick-Connect Fittings: Connecting
- Inspect the quick-connect fitting body and Diesel Exhaust Fluid (DEF) system components for damage. Replace as necessary.
- Prior to connecting any quick-connect fitting to components, check condition of fitting and components. Clean parts with a lint-free cloth. Lubricate with clean engine oil.
- Insert the quick-connect fitting onto the DEF system component until the built-in stop on the line or component rests against the back of fitting.
- Continue pushing until a click is felt.
- Verify a locked condition by firmly pulling on the quick-connect fitting connection of the fuel system component.
