[V8] Heater Box hose leak.

[Mark Kalbskopf]

Steve,

thanks.

I was going to replace the rubber O-ring connectors too, but it looks  
like I'd have to take off the whole inlet manifold to get at them, esp  
the one by the thermostat.

I think I'll leave the heater core in for now. I remember changing the  
blower motor on the 5000 some years back and that was a big pain.

Any ideas where to get the two heater hoses from?
No one seems to list the "Feed water pipe to core"  one.

Mark.
