Type 2 DEF Tank
Type 2 DEF tanks are supplied by the Original
Equipment Manufacturer (OEM). Type 2 DEF tanks
are not supplied by the engine manufacturer.
The manifold (DEF) is supplied by the engine
manufacturer.
The manifold (DEF) must be installed to the DEF tank
as a sub assembly process.
Contact the applications engineer for the engine
manufacturer if type 2 DEF tank and associated
components are to be installed.
Diesel Exhaust Fluid Lines
The diesel exhaust fluid lines must be installed with
the following conditions:
• Be routed as direct as possible with no excessive
dips or sags
• Be routed to avoid abrasion and overheating
• Be adequately supported and not impose stress on
the connector. The maximum clipping details are
detailed in table 4 .
• Must fall within the length guidelines in table 5 .
• Allow for relative movement between the two
components, DEF tank to DEF pump, DEF pump
to DEF injector
• Do not exceed the minimum bend radii. Refer to
table 6 for more information.
