FSB 234-014, Fuel Tank Ventilation Filter
(May 2012)
VOLVO Trucks is introducing a fuel tank ventilation filter kit to prevent erosion of the engine
fuel injector tips on VN, VHD, VT, and VAH truck models. The fuel tank ventilation filter
is primarily designed for use in harsh, abrasive and dirty environments. The fuel tank
ventilation filter is added to the fuel tank vent lines and mounted on the stanchion exhaust
bracket at the right side of the truck. For single or dual tank applications, the vent-lines will
run from the tank vent fittings to the fuel tank ventilation filter. Stand-off brackets and cable
ties will be used to secure the vent-lines. Rubber tubing over the vent-lines will be used to
prevent chafing by the rear deck plate/frame.
Note: To ensure the effectiveness of the fuel tank ventilation filter system, the fuel tank
ventilation filter must be changed at the same interval as the engine air filter.

DANGER
Do not attempt to repair or service this vehicle without having sufficient training, the
correct service literature and the proper tools. Failure to follow this could make the vehicle
unsafe and lead to serious personal injury or death.
CAUTION
Possible damage to electronic components. Turn the vehicle ignition switch OFF before
disconnecting or connecting any electronic components. Failure to de-energize circuits
may result in permanent damage to electronic components.
1 Disconnect all cables from the negative (ground) battery terminals to prevent personal
injury from electrical shock and prevent damage to electrical components.
2
Install filter on manifold, install fittings (with Thread Sealant) on manifold in the correct
orientation, and tighten fittings.
