Gash found on water pump output hose

did you figure out how the gash got on the pipe?

No idea but potentials are: 75K wear and tear plus sharp rock or gravel kicked up from front tire

Been looking at protective options, BB - belly pan might be best of all. Anyone in US got a used one for sale?
 
How about installing a home made mud flap on the rear of the fender? That may be easier.... and cheaper. A simple piece of black plastic cut from an indoor waste basket? Use Epoxy to attach it to the inside lip of the front fender (after cleaning it good first)?
 
A belly pan will change the look.. 'course you might like the pan look! a protective sheath on the pipe will be practically unnoticable..
