Fuel Tank Ventilation Filter
VAH, VHD, VN, VT
FSB 234-014, Fuel Tank Ventilation Filter
(May 2013)
VOLVO Trucks North America has introduced fuel tank ventilation filter kits for increased
protection against fuel injector tip erosion. Two kits are available: kit number 21882780
designed for use in harsh, abrasive and dirty environments and kit number 85136403
designed as a simple but effective installation alternative that can be used in other
environments.
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.
Exhaust Stanchion-Mounted Ventilation Filter Kit Number 21882780
For this kit, 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 both 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.

Fuel Tank Mounted Ventilation Filter Kit Number 85136403
For this kit, the fuel tank ventilation filter is mounted directly to the fuel tank J- bracket. This kit
contains all parts needed for installation on the J-bracket of one tank, therefore two kits are
required for dual tank applications.
