Steel Fuel Tubes
CAUTION: The use of copper tubing is not recommended due to fuel contamination.REMOVAL
1. Perform fuel pressure release procedure.
2. Drain the fuel from the fuel tank .
3. Disconnect the tube(s) at the fuel tank and at the engine. Remove the tube(s) from the holding clips along the underbody. Remove all damaged hoses and tube sections.
INSTALLATION
1. Cut a new section of tubing to approximately the same length as the section to be replaced, allowing for the threaded connectors/fasteners.
2. Bend the tube section to conform to the contour of the original tube.
3. Square the ends of the cut tubing with a file. Remove burrs. Blow out any particles with compressed air.
Ferrule:
4. Position the tubes in the underbody clips. Do not tighten at this time.
5. Assemble the fitting by sliding the nut over the tubing with threaded (open) end out.
6. Slide the ferrule on the tubing with the cutting edge out; the large head end should be inside of the nut.
CAUTION: Make sure that ferrule is assembled correctly before installing it on tube.
7. Lubricate the ferrule and the threads on the fasteners with clean engine oil.
8. Bottom the tube in the fitting and tighten the nut until the ferrule just grips the tube. When the tube can no longer be turned by hand, the ferrule has started to grip the tube.
9. After the ferrule grips the tube, tighten the nut one full turn.
NOTE: After disassembly of the flareless fitting joint, such as at the fuel hose to fuel tube connection, the flareless fitting can be reassembled. To reassemble, reconnect the threaded fitting and seat the ferrule to be finger-tight. When the ferrule is seated, draw the nut up approximately one-sixth to one-third of a turn with a wrench to complete the tightening operation.
10. Tighten the fuel tube to the underbody clips to secure the fuel tubes.
11. Fill the fuel tank. Start engine and check for leaks.
12. Pressurize lines and check new joint for leaks.
