4.Carefully place the element back into the fuel pot. Be careful not to allow any dirt to stick to the ele- ment.
5.Reassemble the filter pot and tighten the ring screw at the top.
6.Open the fuel cock and loosen the two air vent plugs a few turns. When bubbles no longer appear around the plugs, screw them back in.
7.Bleed the fuel injection pump. (See the next sec- tion.)
BLEEDING THE FUEL SYSTEM: You will need to bleed air from the fuel system any time the fuel filter or fuel lines have been detached and refitted; after the fuel tank has been run out of fuel; or before using the engine after long storage. Bleed the fuel system as follows:
CAUTION
To avoid personal injury, do not bleed a hot engine. This could cause fuel to spill onto a hot exhaust man- ifold, creating a danger of fire.
1.Fill the fuel tank. Open the fuel cock.
2.Loosen the fuel filter air vent plugs a few turns. See Figure D.2. When bubbles no longer appear, tight- en the plugs.
3.Open the air vent cock on the top of the fuel injec- tion pump. See Figure D.3.
4.Move the fuel feed pump lever by hand.
5.When bubbles no longer appear around the air vent cock on the injection pump, close the cock.
NOTE: Always keep the air vent cock on the fuel injection pump closed except when air is vented. Opening the air vent cock may cause the engine to stop.
