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 1 .
• Must fall within the length guidelines in table 2 .
• 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 3 for more information.
