Vetus 320VTNEB Fuel Filter/Water Separator

General Information

The Vetus 320VTNEB fuel filters/water separators feature a unique and patented filter with three filtration steps.

1. Firstly, 80% of solid dirt particles and water, which is heavier than fuel, are collected in the transparent collection basin.

2. After this, the fuel flows upwards. Water and solid dirt particles are separated by means of the coalescence effect (coalescence: the merging of microscopically small fluid droplets into a larger drop) and also collected in the transparent collection basin.

3. Finally, the fuel flows further upwards through the filter medium, whose primary function is to hold back the smallest solid dirt particles and water. This ensures a high degree of filtration and a long lifetime for the fine filter on the engine.

Installation

Note: Bear in mind the regulations that your local authorities have imposed regarding the specification and installation of fuel tanks and pipework.

Layout

Interpose the fuel filter/water separator in the fuel supply pipe, between the fuel tank and the fuel feed pump.

To avoid the fuel tank emptying out should a leak arise somewhere in the fuel line to the engine, a shutoff valve should be fitted near the tank's suction connection.

Connection Components Supplied

Two M16 x 1.5 hose bosses with connections for 10mm hose and 3 M16 x 1.5 blind plugs.

Installation Examples

The following diagrams illustrate typical installation setups:

• Diagram 1 (Top): Shows a fuel system with a fuel tank (3), a shutoff valve (2), a fuel supply pump (4), and the Vetus Fuel Filter/Water Separator (1) installed between the pump and the engine. The flow direction is indicated by arrows: Fuel Tank ➡️ Shutoff Valve ➡️ Fuel Supply Pump ➡️ Fuel Filter/Water Separator ➡️ Engine.
• Diagram 2 (Bottom): Shows an alternative setup with a fuel tank (3), a non-return valve (5), a fuel supply pump (4), and the Vetus Fuel Filter/Water Separator (1) installed between the pump and the engine. The flow direction is indicated by arrows: Fuel Tank ➡️ Non-return valve ➡️ Fuel Supply Pump ➡️ Fuel Filter/Water Separator ➡️ Engine.

Maintenance

Draining Water from the Water Separator

Drain the water collected in the water separator monthly. If the transparent collection basin indicates a large amount of water, you will have to drain it off more frequently. See illustration 3.

Replacing the Filter Element

Replace the filter element at least once a year or every 200 engine hours, whichever occurs the sooner.

Procedure:

• Acquire a replacement filter element.
• Stop the engine and shut off the fuel supply.
• Undo the spin-off filter element with a dry hand or a coarse cloth.
• Loosen the screws with which the metal protective basin is fixed to the filter element.
• Fix the metal protective basin to the new filter element.
• Fill the new filter with sufficient clean fuel.
• Apply a thin layer of engine oil to the O-ring and tighten the filter hand-tight.
• Do NOT use tools to tighten the replacement filter.

Illustration 4 Description:

• 4.1: Shows the filter element attached to the filter housing.
• 4.2: Shows the old filter element being unscrewed, with a container to catch residual fuel or water.
• 4.3: Shows a new filter element being screwed on by hand.

Bleeding the Fuel System

Most engines nowadays are self-bleeding. If this is not the case, you will have to bleed the system yourself after having drained off the water or having replaced the filter element.

Fill the new filter element with clean fuel, fit the element, and let the motor run at half throttle for 30 seconds.

Alternatively: Use the manual lever on the fuel feed pump to allow manual bleeding.

Technical Data

Maximum capacity is determined assuming a pressure of 0.1 kg/cm² (3 in Hg) with a new filter element and good quality fuel.
