5. If necessary, remove screws (3). Remove advance device end plate (4) .

6. Drain the fuel for the fuel injection pump. Ensure as much fuel has been drained from the fuel injection pump as possible.

7. If necessary, install advance device end plate (4). Install screws (3) to advance device end plate (4). Tighten screws (3) finger tight.

8. Install timing device closing plug (2). Tighten timing device closing plug (2) finger tight.

9. Install outlet connection (1) on the return fuel outlet of the fuel injection pump. Tighten outlet connection (1) finger tight.

10. Plug or cap all open ports with suitable plugs or caps.

11. Wrap the fuel injection pump in a sealed compatible plastic bag. Ensure that the fuel injection pump is contained within a strong outer packaging with non-conductive, compatible inner cushioning material to prevent movement of the part in the box.
