[V8] coolant hose

[Ed Kellock]

Have been losing coolant slowly for some time in the 1990 V8.  At least one
of the two hoses that goes from the engine to the heater core is leaking.  I
think it's just the feed hose, the upper one as seen at the back of the
engine.  It looks like i has a pinhole leak.
 
I'm wondering if I can "fix" it by cutting and splicing or if I should
replace, and if so, how difficult a job that is.
 
Anybody have any experience with this?
 
Thanks!
Ed
