I know the head is different, but that is only for the SLS pump mounted to the front.
The water pump housing is the same. this is the hose from the housing to the aux water pump.
the hose picture I posted, the "J" hose fast lane part# W0133-1633703 is NLA or stocked. this one might be a Calif 85 hose only, which mine is.
In All Part express this hose comes up for the 300D part# mbz01-3370 $26.73
nothing for the 300TD
