REMOVAL & INSTALLATION
See Figure 1
- Perform the fuel pressure release procedure outlined in this section.
- Disconnect the negative battery cable.
- Clean the fitting(s) of any dirt or foreign material before disconnecting.
- To release the fuel system component from the plastic retainer ring type fitting, firmly push the fitting toward the component being serviced while firmly pushing the plastic retainer ring into the fitting. While the plastic ring is depressed, pull the fitting away from the component.
The plastic retainer ring must be pressed squarely into the fitting body. If the retainer is cocked during removal, it may be difficult to disconnect the fitting. To aid in removal, it may be necessary to use an open-end wrench on the shoulder of the plastic retainer ring.
- After disconnection, the plastic retainer ring will remain with the fitting connector body.
- Inspect the fitting connector body, plastic retainer ring and fuel system component for damage. Replace if necessary.
- Using a clean, lint-free cloth, clean the fuel tube nipple and retainer.
- Before connecting the fitting to the fuel tube, coat the tube nipple with clean 30-weight engine oil.
- Push the fitting into the component being serviced until the retainer seats and a click is heard.
- Make sure the retainer locks securely into the fitting by firmly pulling on the fuel tube and fitting to ensure that it is fastened.
- Connect the negative battery cable.
- Start the engine and check the system for leaks.
