Information:
Remove the smaller hex nut (15.88 mm) (10) from the new 396-0380 Coupling along with ferrule (11) and ferrule (12). Orient the parts as shown in Illustration 3. Loosely install the parts onto the existing half of the 396-0380 Coupling on the engine. Refer to Illustration 4. Do not tighten the nut at this time.Note: Failure to orient the ferrules as shown in Illustration 3 will result in leakage and the need to replace the parts.

(14) 485-1630 Hose As
Push the quick-connect end of hose (14) onto the fuel pump drain line tube. An audible click should be heard and the fuel line should stay attached when gently pulled.

Illustration 8 g06054107
Lift the tube end of hose (14) and place the hose into the connector nut as shown in Illustration 8. Hand-tighten the nut, only.
Loosely secure the two clips with new bolts (16) and washers (17).
Illustration 9 g06054123
Mark the tube connector nut at the 6 o'clock position.
Illustration 10 g06054127
While holding the lower fitting stationary with another wrench and pushing the tube downward, tighten the nut one and one-quarter revolutions until the mark is at the 9 o'clock position. Refer to Illustrations 8,9, and 10.
Once the fitting is tightened, tighten bolts (16) securing the two clips (Illustration 7). Tighten the vertically mounted bolt first, then tighten the horizontally mounted bolt. Tighten each bolt to 25 2 N m (18.5 1.5 lb ft).
Reuse the existing hardware and reinstall the secondary fuel filter base. Tighten the bolts to 45 5 N m (33 4 lb ft). Hold the filter base vertical while tightening the bolts.

Hose release orientation
(22) 485-1627 Hose As
Install hose (22) on the pump. It is important to note that the plastic release must be rotated so the flat is aligned with the body of the pump. Refer to Illustration 12.
Install connector (25) and O-Ring (26) at rear port (21). Tighten the connector to 30 2 N m (22 1.5 lb ft).
Install the new 228-7089 O-Ring Seal onto the connector. Then, install the other end of hose (22) to the connector. Holding the hose angle at approximately 5 degrees clockwise from vertical down, tighten the hose to 30 2 N m (22 1.5 lb ft).
Install a new 228-7100 O-Ring Seal onto the 8T-7487 Connector and install at front port (20). Tighten the connector to 30 2 N m (22 1.5 lb ft).
Install the new 228-7088 O-Ring Seal on the 8T-7487 Connector.
