FUEL

SYSTEM

Diesel Fuel

Use

No.2

diesel fuel with a cetane rating

or higher. Never use kerosene or home heating oil since

these fuels do not have the same lubricating properties as

No.2

diesel fuel.

In cold weather particularly, water vapor

produced

condensation when air is present in the fuel tank.

Keep fuel tank(s) full and completely free of dirt and water.

Fuel

FilterlWater

Separators

A primary fuel filter

the water separating type must

installed between the fuel tank and the engine. This is to

remove water and other contaminants from the fuel before

they can be carried to the fuel system on the engine.

Most installers include with the generator installation

package a

type

filter/water separator for they are aware

the problems contaminants in the fuel can cause - all of

which are not warrantable through Westerbeke.

A typical fuel filter/water separator

illustrated at the

right. This is the Raycor Model

220

Keep in mind that

a water separator type filter is not installed between the

fuel supply tank and engine-mounted fuel system, any

water in the fuel will affect the fuel pump, engine filter,

and injection equipment. The owner/operator is

responsible for making certain the

fuel

reaching the

engine's injection equipment is free

impurities. This

process is accomplished

installing and maintaining a

proper filtration/separation system.

In addition, any gasoline in the

fuel

system will damage

the engine's fuel injection pump assembly and injectors

gasoline does not have the same lubricating qualities

diesel fuel.

Priming

the

Fuel System (Self-Bleeding)

The Westerbeke self-bleeding fuel system is semiautomatic in operation. The self-bleeding feature

the

fuel system allows for easy servicing

the fuel filters. Simply remove and replace the filter element (take

care in catching any fuel that may drain out

the fuel filtering assembly as described in the "Replacing

the Fuel Filter Element" section. Energize the

PREHEAT switch to allow the electric fuel pump to

operate for

20 to

seconds to prime and bleed air from the system.

(No

fittings should be opened.)

Then proceed to start the engine as

you

normally would.

the engine does not start, stop and wait a

few

moments, and then repeat the bleed procedure as indicated below. When the PREHEAT switch is

depressed, the preheat elements (the glow plugs) are energized,

take care not to overheat them.
