vetus FTL3808B Connection Kit for Fuel Tanks
Introduction
This manual is for the VETUS (rigid) plastic diesel fuel tanks. These tanks comply with the requirements according to ISO 21487.
NOTE
Refer to the tank’s installation manual. Ensure proper venting so that the
tank is pressure-free at all times.
Installation
General
When choosing a location for the tank and a place for the deck filler cap,
take the following into account: The filler hose must be kept as short as
possible, it must run continu-ously to the tank and be as straight as
possible. Instead of just one tank, it is also possible to distribute the
total ca-pacity required over two or more tanks. Depending on the way
connected, there are two possibilities:
- The two tanks are filled and used as one large tank.
- The two tanks can be filled and used independently but they can also be used as one large tank.
In the case of a twin-engine installation, it is strongly recommended that a separate tank is installed for each engine. The fuel supply pipes should be fitted in such a way that in the case of an emergency, either of the tanks can supply both engines. Each tank must be fitted with a filler connector and air- relief.
Distribute the tanks, and thus the weight, evenly over the ship (F = Fuel, W = Water).
Positioning
Install the tank in such a way that it is easily accessible for inspection.
The tank should always be installed above the maximum bilge water level. Also
ensure that there is sufficient free space at the top of the tank for the hose
connection. This connection must be easily reached during installation. For
ventilation, the tank should have a free space of about 1 cm (3/8”). from
bulkheads or other tanks
Make sure the tank has a sufficiently secure foundation on which to install it and secure it properly. The dimensions of the tank will increase a little when it is filled. Take this into account when fixing the tank. Fix the tank securely with the fitting straps from the installation kit; these will accommodate the expansion of the tank.
Fitting in sailing boats
When fitting remember that the filler hose must always be positioned on the
same side of the boat as the tank. This prevents too high a pressure from
possibly occurring in the tank when sailing heeled.
Cutting the hole for the connector lid
Position the connector lid on the top face of the tank. If a VETUS tank is
used, then it should be fitted with plug P on the top and the connector lid
should preferably be located so that plug P is removed when the hole is cut.
Cut the hole in the tank and remove all burrs.
Note!
Drill an exactly round hole using a hole saw (ø 114 mm, 4 1/2” diam.). This is
essential in order to achieve proper sealing. A ø 114 mm hole saw is available
from VETUS under art. code VSAW114. Clean the inside of the tank before
fitting the connector lid.
Rubber seal to be applied
Determine the thickness of the wall of the tank and use the indicated rubber
seal.
Installation of connector lid for 8 and 10 mm supply and return pipe
-
Connector lid (5)
Position connector lid (5) into the hole in the tank. Tighten each of the 3 screws (6) one (-1-) revolution (clockwise) and check if the lid can be rotated easily by hand. Repeat this until the lid can’t be rotated anymore. Check that the inlet connection is facing in the required direction. Then tighten each of the screws another three (-3-) revolutions. -
Fuel supply line (1)
Fit the compression coupler (7) with sealing washer (8) into the lid, cut the suction pipe to the correct length – the lower end of the pipe should be 10 – 15 mm (3/8 – 5/8”) above the bottom of the tank – and fit the suction pipe in the compression coupler. -
Fuel return (2)
Fit the hose pillar with sealing washer (8) into the lid. Fit the supplied blind plug (9) if the fuel return connection is not being used. -
Tank vent (3)
Fit the hose pillar with the sealing washer (8). -
Earth connection (4)
Fit the terminal tag. -
Blanking plate/sender for fuel level indicator (10)
Fit either the blanking plate or a fuel level indicator sender; always use the gasket (11).
Note!
Check the tightness of all connections before filling the tank.
Installation of connector lid for 15 mm supply and return pipe
-
Fuel return (2)
Fit the compression coupler (7) with sealing washer (8) into the lid, cut the return pipe (2) to the correct length.
Note!
The return pipe consists of two parts; the end of the curved lower portion should be located about 20 mm (3/4”) from the tank bottom and face away from the fuel suction pipe. Fit the return pipe in the compression coupler.
-
Connector lid (5)
Position connector lid (5) into the hole in the tank. Tighten each of the 3 screws (6) one (-1-) revolution (clockwise) and check if the lid can be rotated easily by hand. Repeat this until the lid can’t be rotated anymore. Check that the inlet connection is facing in the required direction. Then tighten each of the screws another three (-3-) revolutions.
-
Fuel supply line (1)
Fit the compression coupler (7) with sealing washer (8) into the lid, cut the suction pipe to the correct length – the lower end of the pipe should be 10 – 15 mm (3/8 – 5/8”) above the bottom of the tank – and fit the suction pipe in the compression coupler.
-
Tank vent (3)
Fit the hose pillar with the sealing washer (8). -
Earth connection (4)
Fit the terminal tag. -
Blanking plate/sender for fuel level indicator (10)
Fit either the blanking plate or a fuel level indicator sender; always use the gasket (11).
Note!
Check the tightness of all connections before filling the tank
Connecting the tank
-
Filler cap
Fit the filler cap (13).
Tip!
When filling the tank, fuel can overflow from the filler cap and spill onto the deck. This can be prevented by installing a VETUS Fuel Overflow (11) between filler cap (13) and tank. Consult the relevant manual for installing the VETUS fuel overflow -
Filler hose
Fit a filler hose (6) between the filler cap and the tank. Use a fire- resistant hose with an internal diameter of 38 mm (1 1/2”)or 51 mm (2”). Install this hose in such a way that neither tank or filler cap are mechanically stressed. -
Breather nipple
Fit the breather nipple (7) as high as possible above the level of the top of the tank.
Warning
Choose a location for the breather nipple at a place where leaking fuel or vapour cannot get into the ship! -
Tip!
Unpleasant smells may escape from the air breather nipple. This can be prevented by installing an active charcoal filter (VETUS Odour Filter (10)) in the vent hose (8). Consult the relevant manual for installing the VETUS odour filter. -
Vent hose
Fit the vent hose (8). Use a fire-resistant hose with 16 mm (5/8”) internal diameter. When viewed from the tank, the vent hose should be fitted in a continuously upwards slope. -
Fuel supply and return
Connect the fuel supply (1) and the fuel return pipes (2) to their respective fittings. Fit all hose connections using 2 stainless steel hose clamps! All metal parts in the fuel system must be earthed in order to preventsparks caused by static electricity. Connect an earth wire to the contact tongue (5) on the connector cover. Also connect an earth wire to the filler cap. Use yellow/green insulated wire with a core cross-section of at least 1 mm2 ( AWG 16).
Check
Check the system for any leaks. Extraction pressure 20 kPa (0.2 bar)

Sticker
Apply the red ‘Diesel fuel tank’ sticker on the tank, the text must bereadable
after installation of the tank and also affix the content sticker.
Preparing for winter
It is advisable to fill the fuel tank with fuel completely during the winter period in order to prevent condensation. Water droplets in fuel are the ideal transporters of dirt and rust through narrow pipes. A full fuel tank prevents the growth of bacteria in the tank
Maintenance
- Regularly check the air relief nipple and clean the sieve in the nipple if necessary.
- Every year, check the hoses and hose connections for possible leakage and fit new hoses and/or hose clamps as necessary.
- Also check the tank for damage caused by chaffing. Replace a damaged tank immediately
