Paccar SPN: 4356 - Aftertreatment 1 Diesel Exhaust Fluid Line Heater 3

[@romper4444]

Just a tip from a mechanic for you guys running into this, u can take the plastic casing off the end of line and inside you'll find the heater wiring, it always breaks inside that plastic casing where wiring wraps around end of hose. You can take apart each end until u find broken wire, repair the wire and reinstall. Easy fix and no need to replace Def hose!
