Depending on the engine type, there are 2 types of fuel pumps. On HCS engines, the fuel pump is driven by a lever, one end of which rests on an eccentric projection on the camshaft, and the other controls the diaphragm of the fuel pump. On CVH engines, the fuel pump is controlled by a separate pusher, which is driven by an eccentric projection on the camshaft and with its other end acts on the pump drive lever. Fuel pumps are non-separable and have a nylon filter. A flap is installed in the air filter housing, which controls the temperature of the air entering the engine. In one case, heated air comes from the exhaust manifold, in the other - from the front of the engine compartment.
Caution: Many operations performed on the fuel system involve removing fuel lines and connections that may cause fuel leaks. Gasoline is a flammable liquid, so care must be taken when working with it.
