NOTE: Remember to install the new O-rings into the inlet and outlet of the fuel injector assembly, using the seal retainer tool.

1. Apply a few drops of clean engine oil to the male tube ends.
2. Connect the fuel feed and return pipes to fuel assembly.
3. Install the fuel pipe retainer and attaching nuts. Once installed, pull on both ends of each connection to make sure they are secure.
4. Install the rear fuel pipe clip retaining bolt.

Tighten
- Tighten the rear fuel line bracket bolt to 6.O Nm (53 lb. in.).
- Tighten the fuel pipe retainer nuts to 3.0 Nm (27 lb. in.).

5. Install the new O-ring seals on the engine fuel feed and return pipes.
6. Connect the fuel feed and return lines to the engine fuel pipes.

Tighten
- Tighten the fuel pipe nuts to 30.O Nm (22 lb. ft).

As soon as I had submitted the question, and was filling out the form, I got it figured out. Thank you for your reply. It was right on. Had a really hard time finding any relevant illustration on the internet, and was at my wit's end. As it turns out, I had the sequence perfect, but had an extra oring in the return side......which screwed everything up. Works perfectly now... Thanks for your reply. 5 stars.
